afterflow
The fulfilling, tranquil feeling after taking a massive piss.
Dude I held that piss in for an hour, but after I launched it, the afterflow was so worth it.
Afterflow
The flow of water at the base of the waterfall, after it has fallen from the top. Usually moving water and sometimes looks foaming.
“The leaf got caught in the afterflow of the waterfall.” “They swam in the afterflow of the waterfall.”
