The act of shitting into a used condom and leaving it on display in someone's home.
Remember that Tylerkid that fucked with me in middle school? He threw an open house on Saturday, so I banged his gf and left a stinky potato behind his mom's lamp.
A position where a person takes a shit then dips his nuts in his own feces, and then sets his balls on his partners forhead while yelling, "STANKY POTATOS"
