Hell Grind
I may exaggerate a bit here, and combine a number of games, and make some of it up but this is a generalization/trend:
Typically found in a sandbox type game. All grind is often reset upon updates so you must start again from the very beginning. That's okay though because some hero out there has uploaded a save file for you at the point where you would be at the previous update. Unfortunately, you skipped 1 update so you want to go back to before that and can't find a save from back at that point so you say screw it and just start the whole game over again.
You skip through the grind as fast as you can at the beginning of the game. This is not your first rodeo, and you know what you are doing. Skip skip skip, and even while skipping this can take a fair bit of time.
Okay finally you have caught up to where your old save files should be and you are on all new content. (new for you. You are an update back after all) It turns out in this update you can get a blowjob from the hot waitress. You heard in the comments that she doesn't forget the balls, so fuck you she doesn't forget the balls you are in it to win it! You are gonna get that blowjob no matter what!
In order to get that blowjob, from the waitress you need to defeat the cook at the restaurant that knows kung fu. Well, shit, you have 0 fighting skill and with 0 fighting skill, you have 0% chance of defeating that cook. So, you ask around and look for clues to find out where to learn how to fight. Ignore the baseball bat in your room that you picked up in inventory that could not possibly help you in this fight with the kung fu cook, and that is to be used in another mission to get an apple out of a tree. You figure that the monk that is training in the gym is a good spot to check first in learning fighting skills. This monk can only teach you dexterity and not strength and what you need for this fight is strength.
So you wander around looking for where to learn fighting skills and find a karate dojo in the mall. Membership at the karate club is $3000. Damn, that's kinda expensive. You can grind about $100 a day though so it's all good. You grind away an entire month in-game to earn $3000. You take the $3000 to the Karate dojo at the mall and you enter the dojo. After paying $3000 for membership in the dojo the karate master tells you that he will not train you unless you bring him 10 carrots.
10 carrots should be easy peasy. You go grind for a little bit again and go to the grocery store. Carrots are out of stock at the grocery store. So you go back to the old monk at the gym and ask him for advice again. He tells you that you can get carrots from farming. The old man gives you some carrot seeds and marks a spot on your map.
So you now have "Farm" as a location on the map. You go to the farm. In order to make use of this land you must buy a plot of land on the farm to harvest your carrots. This farmland costs you $5,000. Damn it... grind grind grind away for another 50 days in-game to save up $5,000. Finally, after all of that grind, you own a plot of land. You get there and try to plant your seeds. "You need a shovel to plant the seeds"... Damn it.
You go back home and you remember seeing a shovel in your garage before. The shovel is just a piece of the background art and you can not use THAT shovel. That's a snow shovel asshole! So back to the general store you go looking for a shovel. There are no shovels in stock, but they sold the last one to the janitor at the school.
You break into the Janitor's house but he wakes up and scares you off before you can get the shovel. He doesn't recognize you. So you realize you need to make the janitor go to sleep more heavily so you steal some sleeping pills from your mom's medicine cabinet and put them in the janitor's thermos. Success! He sleeps like a baby and you steal his shovel.
You take the shovel back to the farm and plant the carrot seeds. No, you can not smash the kung fu cook with the shovel I tried. So, you finally get your farming on but the carrots keep getting stolen before it's harvest time. There goes another in-game couple of weeks. You are really dying to get that blowjob from the waitress at this point as you recall she does not forget the balls! For the balls! You power through. You go talk to the old monk again and tell him about your carrots being stolen. He gives you a hint that it could be the rabbits. You search around the forest for the rabbit hole and find the king rabbit. There are carrots all over the place but you can't take these carrots. You kill the king rabbit and use it's corpses as a scarecrow to scare off weaker rabbits from eating your carrots.
Finally, success you got your 10 carrots so it's go time for getting your karate training fuck ya! So you take the 10 carrots to the karate master in the mall dojo and you learn lesson 1 of karate.
You must complete 3 lessons of karate from the karate master to beat the kung fu cook. The karate master wanted carrots last time now he wants a picture of your mom naked. So you have to buy a camera, but you are out of sleeping pills now so need to buy more of those along with some wine and a few months of grind later you give naked pictures to the karate master.
2/3 karate lessons learned. Time for that final lesson! This lesson for some reason involves a minigame that is a word game. YOu do the minigame and finally have the karate skill to beat kung fu cook.
You go to fight the kung fu cook and lose. Your strength stat isn't high enough to win that fight in spite of knowing the karate moves. So you go back to the gym and hit the punching bag. After a month of training at the gym every day punching the punching bag you are finally ready to fight the Kung fu cook.
You fight the Kung Fu Cook, and the waitress is pleased. You may now visit her on the beach every Saturday. You go to the beach, but you don't have any tanning lotion or a swimsuit. You must grind again to get these 2 things that are needed for the beach. Finally, you get the opportunity of building 1 love point each week with the waitress. You only need 10 love points to get that blowjob so it's on. You play minigames at the beach for a few months to build those love stats up finally blowjob time. She didn't forget the balls!
