What is Do A Barrel Roll!?
1.
Comes from Starfox 64. A character would command fox to do a barrel roll in order to prevent being shot to deadness.
A barrel roll is when a fighter pilot makes his ship turn over, very quickly, in mid-air. It makes the wings harder to hit.
It's more common practice to shout this phrase at friends while they play video games. Especially if they can't do anything roll-like. The purpose is to be obnoxious, and quote old video games. Two of most peoples' favorite things.
"Son of a white boy, my Sim will not stop crying!"
"Quick, do a barrel roll!"

The controversial quote Optimus Prime is going to say in the upcomming Transformers Live Action Movie. The quote was submitted into the "Make Prime Speak" Contest and is currently by far, holding first place (Thanks to the YTMND Community) among a myriad of other crappy submitted quotes.
Some Flying Transformer Dude: OH NOES!!! I'M UNDER HEAVY FIRE!!!
Optimus Prime: Do a barrel Roll! lol
