A defecatory condition whereby the subject, after just previously taking a rampant and usually excessively volatile and suspiciously aqueous shit, is compelled to perform a re-shit moments later with very little prior warning.
'Jake, watch my beer I gotta go to the shitter'
'Radek, you just went like 5 minutes ago'
'No Jake, I got The Aftershits'
'Dude, is it because of the bape?'
'Yes Jake, I got baped hard.'
