Barrel roll
From lurkmore wiki
An aerial combat maneuver in which a fighter plane spins clockwise or counterclockwise while still flying forward. By 2006, the line "do a barrel roll" (a line that Peppy frequently shouts in the game Star Fox 64) is ubiquitous on /b/. In the game, your fighter is invincible while barrel rolling.
"Do a barrel roll," like "stick it in her pooper," is often used as a stock reply when someone asks for advice (usually with the tagline "What do I do, /b/?", a reference to the "IF THIS IS TRUE THEN HERE IS WHAT YOU DO" incident) on /b/.
Often used during phone-in raids on TomGreen.com Most famously used by "Xenon" [1]
Ironically, the "barrel roll" depicted in the game is actually an aileron roll.
