look up any word, like pussy:
 
1.
Kind of like SMH Shake My Head but it's something more classy & sassy! WMHBAF Whip My Hair Back And Forth is something you would say after you pwn someone at League of Legends.
LOLOLOL, you guys got owned, you should uninstall scrubs! WMHBAF!

"Whipping My Hair Back and Forth"

The happy equivalent to SMH (shaking my head)

This word is used out of joy, or whenever you're feeling like Willow Smith

1. Violently shaking your head backwards and forwards to depict joy
2. Used when encountering haters online
