ok i asked chatgpt and this is what i got if anyone else is wondering:
NTR - Netorare
A Japanese hentai genre focused on infidelity or cuckolding, where the protagonist's partner is "stolen" (netorare literally means "to be taken away while sleeping"). It often emphasizes jealousy, betrayal, and emotional torment, popular in manga/anime but controversial for its dark themes.
SPH - Small Penis Humiliation
A humiliation kink where the performer mocks or belittles the viewer's penis size to heighten arousal through embarrassment. Common in JOI or femdom content, it's all about psychological power play.
BNWO - Black New World Order
A race-play fetish fantasy involving a dystopian scenario where black individuals dominate society (often sexually). It's highly controversial and tied to cuckold/interracial kinks, with roots in online forums—definitely polarizing and not for everyone.
CBT - Cock and Ball Torture
A BDSM practice involving pain or discomfort to the genitals (e.g., slapping, squeezing, or devices). In JOI, it's verbal instructions for self-inflicted torment, but it's intense and requires caution to avoid injury.
