A simple, fun word that has several meanings. Soe examples: "I don't care", "Go away." (when given with a flick of a hand), an unexpected, completely logical answer to ANYTHING, "leave me alone", or occasionally, "I like pie."
For some reason, saying this is debate class gets you detention, although I find it almost always makes more sense than anything those other losers are saying.
person A: you're an idiot.

You can't help but love her. She's hard to deal with at times but she's the real definition of a ride or die. She's a role model and if she puts her mind to it she will achieve it. Sometimes she's misunderstood but she doesn't care. She gets attention from those she wants and don't wants. Boys and girls want her but she never really pays attention. Her exes either hate her or miss her. She's the cool ex that will be there no matter what. Whoever gets or has her heart should keep it because she's the real definition of a trophy . She's the one you don't want to lose whether its relationship or friendship.She's wifey material and whoever marries her is in for an amazing life time with someone who can be their best friend supporter and everything else
Nyahh is your girl
