Dutch tp

It is the act of throwing used toilet paper (toilet paper already used to clean shit from your ass) at any house other than yours. For further effect piss on the Dutch tp afterwards.

*In baseball game
Bill: "Hey Frank I'm going to the bathroom, do you want me to stop at the concessions stand afterwards to get you something to eat"
Frank: "Nah, but what you can do for me is save some of the toilet paper you're going to use in the bathroom. There's this neighbor of mine who pissed on my dog yesterday and I want to get him back for it by Dutch tp'ing his house."
Bill: "Sure thing"
