The disorganized and messy appearence of ones bedroom, which promts the saying "did a tornado come through here?" Is the result of a rather physical night "under the sheets."
Dude 1: dude! This place is a mess! Did a tornado come through here?
Dude 2: with the date I brought home last night, its more like a scorenado came through here!
Dude 1: dude! Nice!
Dude 2: you can stop saying dude now.
