When someone takes a shit in the toilet and it sticks
to the bowl and still is not removed after flushing, therefore
appearing permanent like a tattoo. Shit + tattoo equals shattoo.
Person 1: "Yo hold it dawg let me take a dump"
Person 2: "Okay man"
Person 1: "Ahh nasty dude I can't go in there someone made a
shattoo"
Person 2: "Sorry"
A permanent brown ring around one's asshole gradually developed from lack of proper hygiene after taking shits.
The best way to prevent the acquisition of a shattoo is to use a bidet regularly - toilet paper alone will only rub the shit pigments into the skin surrounding the anus.
Shatoot is very similar to the term Shart, however it is comprised primarily of gas as opposed to fecal matter.
Jenifer:Dude, I heard Lydia shatooting today.
Holly: What the fuck is shatoot?
Jenifer: It's like sharting with a little less shit and a little more toot.
