When you were little you used to attract lots of girls that said "You're so cute!" but in Middle School people whisper that your the weird kid who is riddled with zits and the kid who thinks he knows everything but is really fucking retarded. If you go near anyone, they will kill themselves.
Girl: "You're so cute!"
Boy: "Thank you!"
Boy's Friend: "Oh god, he's a Changie."
A word describing people, usually female, who try changing their partner.
Ray: Yo, Stu... You won't believe what happened today. Rosetta asked me again, to stop smoking weed.
Stuart: I done told you already! That bitch is so changy, man.
Ray: Yeah I know, man... So god damn changy...
It means (Little monkey) usually used to call younger sisters. Sort of like a pet name.
Older brother-Changy!
Younger sister-What??
