Slug Dick 

When a mans penis looks like a slimey slug because his dick is limp, short, smelly and wet looking due to being unwashed for a week.

Slug dick can also be defined as an unerect penis that resembles a curved fat slug.

Oh my goodness Becky, he pulled his pants down to reveal his disgusting slug dick!!!
