Stiffy Jify

A "Stiffy Jify" is when a transgender man gets his boyfriend to spread peanut butter all over his shaft, making it hard. Then the boyfriend sucks him off, licking off the peanut butter at the same time until completion. Once they cum, you take it and put it in two graham crackers like smore's, adding chocolate and more peanut butter and eating it.

"Do you know where Samuel went?"
"Yah, he's in the bathroom giving Michael a Stiffy Jify"
