Aftershock 

When you have an initial crap that comes out fine, then 30 mins later, there is a huge rush of diarrhea. The initial dump must feel complete, not pinched off to qualify.

"Man, I thought I had a no wiper, but i was sitting at my desk later and felt the aftershock coming on."

Aftershock 

Bong terminology. The residual smoke in the bong and it's piping after toking the main hit. Usually, your lungs are too full to take in the aftershock. Checking the density of smoke in the aftershock is a good way to see how good your hit was, but that is pointless.

I gave the aftershock to my homie.
