weiner lump 

The obvious lump exhibited by a man who wears tight or thin pants with no underwear.

"Man...that dirt hippie is wearing camping pants with no underwear. Would you look at that weiner lump? It is a like a leather sack full of nickels."

Weinerdumping 

When you take your penis and stick it in a dump trucks exhaust pipe. When the dump trucks accelerates, smoke will start to flow inside your penis, giving you a temporary high.

"Did you hear what happened to Jim?"

"No, what happened?"

"He went weinerdumping and got a broken dick."
