ROAST BEFF?!?!

Who else is over the whole roast beef thing where guys try understanding vaginas that know nothing. I've been in multiple situations with guys and lesbians to for some reason which striked me odd because they do have vaginas lol but where someone is talking about a girl and then all the sudden they say "oh dude I hope she doesn't have roast beef cause I won't be eating that sandwich" like are you kidding me? Women all have different vaginas it's like the snow flake thing but a little less lol there isn't a perfect vajayjay. I just wish they would know what other vaginas looks like instead of guys seeing one puss that had small libia then expect everyone to be the same. Anyways comment a story of the first time you heard "roast beef" or had a conversation with an idiot about it.
