We All Hate You
WAHU can be an annoying ass dumb bitch, that tries to sleep with everyone, and no-one likes because of it. A stupid cunt that bangs on ones door to try and sleep with them at 8 in the morning.

"Hey WAHU!"

The classic facebook WAHU defriend, where you write WAHU on their wall and then defriend them.
