1.
When an exceptionally massive turd crests out of the water, like a humpback whale.

Similar to a "periscope" (where the end of the turd will stick straight up out of the water).

Both of which, really really stink.

2.
When the end of an exceptionally long turd sticks straight up out of the water.

Similar to a "breach" (where the turd will arch up out of the water) but fully vertical.

Both of which, really really stink.
Dude, I just totally dropped a periscope in there.
