Tits Yeah! 

A positive phrase, used as a replacement for "Fuck yeah!" when appropriate.

It's also a reference to the character Nick from the videogame Left 4 Dead 2, whose most popular phrase is (arguably) "TITS!"

Tadin: "Do you wanna go watch the Rocky Horror Picture Show?"
Cecil: "TITS YEAH!" *high five*
