Gahdonker
A Gahdonker is when a guy has a meaty tool that looks like it could punch a hole in a wall, or a tiny stub that looks like it got run over by a truck.
My cousin has a Gahdonker so big it could be a tent.
He got a Gahdonker so tiny, it looks like he forgot to grow it.
My neighbor’s Gahdonker is so average, it’s basically a chicken leg.
