When you are doing anal with a partner, and said partner has loosened up to the point where feces have begun their journey towards the rectum. Your "John Thomas" is being surrounded with anal butter essentially pickling your schlong. In other words, "Shit-Dickle'ing".
Man: Oh my god what is happening?
Woman: Honey, you're evolving!
Man: NooooOOOooooOOoooo!
Man: You're Shit-Dickle'ing me!
A phrase that can be used when one wants someone to leave, now, esp. if that someone is being annoying to the point of asking for a serious ass beating.
Annoying person: "give me something of value and I will go in peace"
person being annoyed: "you can go in dog shit, dingle balls, I've heard about enough out of you."
