Ass Plundging

The act of vigorous anal sex and without breaking stride occasionally instering into the vagina, in a somesort of random order.

My son clogged the bowl so bad it took forever to unclog, i felt like i was ass plundging.

Yeah so the lucky girl last night wasnt into my whole ass plundging routine, bummer.

Indiana Ass Plunge

First, you have to wait until this person has to take a massive shit, then you put your lips gently on the anus of a male or female and start out slowly sucking and after ten seconds, piss in the anus of that person. Then put your lips back on that person and suck fastly until the person pushes the piss and shit all over your face.

Boy: I just gave my girlfiend an Indiana Ass Plunge!

Friend: Gay.

Boy: No it wasn't, she seemed to like it!

Friend: Probably because you were her first.

Boy: Yeah, you're right...
