look up any word, like cunt:
 
1.
when something is casually thrown out of a window, usually an item of value such as a rolex, or blackberry. Or maybe even a container full of bouncy balls. Pretty much anything you can find, shoes, maps, even plastic dolls. It doesn't matter, everything's better once you fucking window it.
Often used when describing a mental out of control party thrown by an amazing girl.
"Just fucking window it mate!"

"DID YOU JUST WINDOW MY BROTHERS ROLEX?!?!"

Person 1: "Anyone seen my shoe?"
Person 2: "I think someone windowed it"
