look up any word, like kappa:
To own someone by way of chair rage
"Man, once I set up the dreaded chair defense, we just sat back and watched the other team be cha'd."

"I'm about to cha the hell out of these noobs!"

The thing you say when you have a totally different opinion about something but don't want to show it.

Like Sakura from Naruto.
Girl 1) "Does this dress make me look fat?"
Girl 2) "No, it looks great! Cha."

Something you say when you see a bro.
IE: someone wearing Thrasher, Metal Mulisha, SRH, Famous, TAPOUT, ect..
Instead of straight out being like BRO ALERT. all you need to say it "cha"
*guy in puffy skatershoes, high socks, dickies, and a Tapout shirt struts into the store*
you glance to your friend, and they glance back. nothing but a simple stare and a quick, "cha" ahha "cha".

explains it ALL.
Bros often say CHA, cha man, cha bro, what sup, cha!?

Meaning messed up or obviously stupid - DUH!!. A reference to the villian "Chairface Chippendale" in the Cartoon "The Tick". Chairface is responsible for the CHA written on the moon throughout the comic and cartoon series; he was trying to carve his name onto the moon with a giant heat ray built by Professor Cromedome but was stopped before he could finish.
When someone does something stupid..Cha!
