Input: Text: i was in heavy traffic. "heavy" is a variable term as i live in a very small town, but it was 12:05ish and there were more cars on the road than usual. so i'm driving down one of the main avenues that has two lanes and doing as i should, but this one guy in a jeep decides to mess up my driving experience. i'm in the center lane, minding my own business and picturing the tim horton's i'm about to consume when this penis-wrinkle violently cuts in front of me. now, i use the word violently literally. like, he had maybe a second or two between success and an accident. i slow down as much as the guy behind me will allow and blast my horn, all while putting my arm out the window the flip this guy the bird...... except i didn't. in my adrenaline rush i flashed the [horns](http://imgur.com/lgxsltl) ... and he put his hand out the window and put up the horns as well as to say "thanks! i know that was a metal thing to do! i'll do it again in the future!"

fuck that guy and fuck my muscle memory.

TIFU by flipping off a stranger.
