Have you ever been to a college party? I'm not trying to make fun of you, really, have you? You can't walk 10 feet through the kitchen without some drunk idiot yelling at 2 equally drunk girls MAKE OUT!!! and them acquiescing.
Now indeed, the message you were responding to about that being normal behavior without sexual connotations; I'd definitely disagree with that, especially in a US college context. But this is hardly something that's removed from reality, especially in the setting of a college world.
However, it certainly does not always have lesbian connotations, as two girls kissing in a spin the bottle game has more to do with them trying to titillate the men than for their own enjoyment. So to answer your original question some pages back, no, the game doesn't have any actual real lesbians persay, only in the college party definition (usually doing it for male attention)
