I/0

One of the most impure, horny, sex-driven individuals to ever grace the planet. Generally a good person until you mention anything remotely lewd. Vehemently denies any allegations, but anyone who's spent more than 14 picoseconds around him can tell it's all a facade.

Not to be confused with I/O.

Uh oh, I/0 is having lewd thoughts again!
