Assvacuation

The act of completely and totally emptying your bowels, most often done in an involuntary manner and inconvenient setting.
May leave you with an empty feeling, or dehydrated.

Man, after being stuck on I-285 for 2 hours, I barely made it home before having a total Assvacuation in my pants.
