look up any word, like sex:
Wtheo ,

A combination of "WTH" (What the hell) and "Heo" (A Vietnamese word meaning pig)

Vietnamese people usually use this phrase because It sounds like "What the hell"

Translated into English, you'd being saying "What the pig"
Examples :
"WTHeo man? What did you do that for? "

Basically the same thing as WTH, just with a Vietnamese twist.
