Can’t decide which of you gets to go to the bathroom first? With the homie dumper you don’t have to worry about it. The homie dumper is a new innovative system where your friend sits on the toilet and takes a shit while you sit facing him, with your legs wrapped around him and shit through his legs into the toilet or the other way around. Never lose friends again over who gets the first shit!
“If you won’t let me use the bathroom first, let’s just take a homie dumper and be back out quicker!”
