Bumbsterbate 

When a homeless man is so lonely and bored, he has to whack it.

Yesterday in McDonald's, I walked into the bathroom and I heard the sound of the bumbsterbate, so there mus have been some dirty beatings going on in there.

To simultaneously masturbate and play with your nipples.

I heard Ashley was about to boobsterbate last night
