Shit-Swoop

Stealing the honor of performing the first bowel movement in someone else's new residence. This is most applicable after you help a buddy move-in to a new place and you just have to go to the bathroom to take a dump.

Andy: "Hey guys, I just totally stunk up the bathroom, be warned!"

Andrew: "Damnit Andy! Why did you just shit-swoop my bathroom? This is my brand-new apartment and I haven't even used the toilet yet!"
