Now you have another excuse for spending a  hours in the bathroom: “What? I was rocking out another mPEE3?” (Yes, actual file name.) Billboard Brasil presents “Guitar Pee” which combines the boring functionality of a urinal with the musical stylings of an electric instrument (hehe, instrument) and amp.

Sure, anyone can shred with their fingers but only real rock gods can cop a deep-knee rock squat and squeeze out some tasty licks with their own urine. Gauntlet: thrown.

Next time you’re in the bathroom, ready for a guitar solo contest, you can look over at the next guy and say “Piss Off!” If you win, start your own (rhymes with rock) band.
