a threesome involving a girl and two guys. one of the guys does the girl from behind while the girl gives the other a blowjob. similar to the eiffel tower except instead of the high five you place your index and middle fingers together like on the television show venture brothers.
something you yell when someone has done something that obviously anyone could do or just something to shout at the library because ur tired of everything being quiet
person: wow!! 2+2 really is 4!!!
you: yay you GO TEAM!
**silence**
you: GO TEAM YEAH! WOOO!!!......sorry spur of the moment type of thing
Bob: "Hey coach, did you know that GYAT means "Go You Athletic Team"? You should tell that to the girls team playing basketballover there for motivation!"

Coach: "GYAT! GYAT! GYAAAAAAATTTT!"
