To defecate inside another human being's anus.
I got you Sharon! Right in there! SLAM DUMP!
Last night Steven took it upon himself to slam dump inside me. It was pleasant.
The immediate release of poop
as soon as you sit on the toilet
after holding it in for a while or after eating too much. Just like a slam dunk
, only done with the ass
Having to take a shit
I went to go eat with a friend the other day. When we go back to the dorm he scurried to the bathroom
, taking small but quick steps. Seconds after he shut the door I heard him shout "slam dump
n. : Unusually large deposit of fecal matter after a long absence of bowl movements, typically followed by an overwhelming sense of relief.
'Yo, I ain't pooped in a minute but I just had this crazy slamdump'.
when you have to take a dump really bad and you get to the toilet and you start to shit before you even sit down, but you still make it
Mike: OH SHIT! i think im running to a SLAM DUMP
