Mary Kate

1) an eating-disorder-ridden, indecisive, eager-to-please perfectionist
2) a sweet, unassuming virgin who is most likely quiet and timid, speaking more with noises (hm, oh, mm) and sound bites (fun, sounds good, whatever you want to do) than actual words, often accompanied by excessive eye-lash batting and pursing of lips. see mary with a twist
3. prude, but with sooo much potential i.e. perfection

1) man you couldn’t decide on what food to order and now you're not eating it.... you going mary kate on me?

2a) i dated some britneys but I'm marrying a mary kate
2b) good luck they are a dying breed....

3a) man, all the girls at this party are whores… wait a second, who’s that hottie?
3b) that’s mary kate. she’s gorgeous, but she’s waiting til marriage.
3a) damn.

mary-kate

an action verb meaning "to vomit"

While I was sitting on my couch, I ate a 3 day-old moldy hot dog and immediately mary-kated all over the coffee table.

Mary Kate

a "Mary Kate" is an ungrateful spineless bitch that acts alot different in public than she does at home. She happens to be a sweetheart on the outside but a cold hearted bitcg when it comes right down to it. she acts differently around different people and can NOT be trusted.

yeah her parents shouldve just named her mary kate
