Hogpen Humdinger 

The act of masturbating onto someone's face at the same time as having your testicles hummed on by another person, while you are all in a twelve-man camping tent and the other nine people are asleep.

Dude, you won't believe what I did on our yearly camping trip last night! I gave a chick a Hogpen Humdinger!!!

Humdinger Speedbag

Cunalingus delivered with an extremely high frequency of tongue movement in a semi-eliptical progression. Varying pressure must be applied to execute properly.

My tongue was bashing up on her clit like a speedbag.. She was definitely getting the ol' Humdinger speedbag special!
