when you take a crap so large it must be flushed twice in order to go down
"i gotta use your bathroom dude, Chipotle is making a comeback"
"ok, dont stink it up"
45 minutes later you hear the toilet flush, then a pause, then flush again.
"whew, that was intense"
"damn dude, if your gonna take a double downer...at least wash your hands"
