1. the odor of shit. shitstink can be mostly found in toilets although is often generated through farting. especially after curry. shitstink is only truly a bad sign when gaping is involved
when you are ready to shit in a public bathroom, yet somebody comes in, and you hold it so that they won't hear embarassing noises coming from you (in essence, you are "sitting still"), and THEN you shit once they leave.
Roger: Hey, Dave! You don'tlook so good.
Dave: Man, someboy came in when I REALLY had to crap, and I had to have a shitstill until they left. It REALLY hurt to have to hold it for so long!
