An impromptu defecation involving an individual (esp. male) who chooses to urinate in a seated position.
Dude, sometimes I just like to pee sitting down because not only is it more relaxing and hygienic, but you never know when the 1.5 will show up.

Pee is 1, and Poo is 2, so 1.5 is diarhhea. Not quite liquid, not quite solid, but everyone's favorite.

The act of taking a piss out of your ass, usually after a night of heavy drinking. Its a combination of taking a #1 and #2 out of your ass at the same time.
