When dropping a deuce, turd, or shit, the Initial Blast is the first bit of shit to come out into the toilet. Mostly used to define explosive diarrhea shits, the Initial Blast can range from one turd to a whole toilet bowl full of turd.
Dude I went to Buffalo Wild Wings today and when I got home I had to shit so bad. The initial blast required 2 flushes to get it all down.
