What's left behind in a bathroom trash can from someone who just wiped their ass. Usually only done by wetbacks who, for some reason, choose to throw their wipings in a can, rather than flush them in a toilet. The topside browner will be facing up, showing the smear.
Dude, those fuckin wetbacks are always leavin behind some gnar ass topside browners.
