look up any word, like twoosh:
 
1.
The name given to girls that aren't popular but have boyfriends that are sort of known by everyone.
"Dude, who's that? I haven't seen her like... EVER. Where the hell did she come from?"
"I think that's That One Guy's Girlfriend, you know, the one that looks like Harry Potter? She's been in the same school as you since 3rd grade, man. Seven whole years."
"No fucking way... Huh..."
And they both continue on their way, only to forget about her.
