In the context of internet communication: "I can't finish the last level of the campaign! Any tips?" "Do a barrel roll."
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.
"Quick, do a barrel roll!"
An expression for what seems to be the solution to almost every impossible situation (in other words, a way of saying there is no solution.)
