Because saying "masturbate in the bath" is just too damn long :.P
Sally: "Ah, there's no better way to relax before bed than putting on some soft music, a little scented candles and a little bathturbating."

Jane: "You really need to get laid more."

Bathturbate
The art of bathturbating. Having a wank in the bathtub.
“Dan seems like he has a really tough time getting laid. I bet he goes home every night, runs a bubble bath and bathturbates.”

The act of masturbating in the shower. It's much harder for someone to be caught doing this, but they'll probably end up using up all of the hot water.
Example 1: Bob has been in the shower for 2 hours now. What's taking him so long? Is he bathurbating?

Example 2: Bathturbation is much easier than normal masturbation. No one will ever catch you in the act!
