When you need to drop a few pounds by having a big dump.
This happens when you've:
1) Just had a big meal
2) Been constipated and need to let one rip
3) Been out all night and don't trust public toilets
John: Ahh man I was out all night and the public toilets were disgusting so when I got home I had to plop a few pounds.

Mat: Dude that's disgusting !!
