When you need to poop really badly, but you hold it in long enough that the feeling passes temporarily.
Example 1:
Ah I really need to shit... Nope, just butt swallowed it we're all good.

Example 2:
One time, I butt swallowed five times in the span of an hour, and when I got home I had to shit so bad that I pooped myself before I got to the toilet :/
