sonic hydrobating

When you use the sounds of other things in your bathroom (the bath filling up, the bath draining, a running blow dyer, the heaters, etc.) to cancel out of the sound of you masturbating in the bathtub. While done successfully 90% of the time, your parents, roomates, girlfriend, (etc.) may become suspicious of extra long baths.

Dude 2: Really dude? What noise did you use
Dude 1: I used a shower speaker and turned it up

Hydrobating 

The use of a source of water (faucet, shower head, whirlpool jet, etc.) to stimulate the genitals in order to produce orgasm. Mostly used by females.

Using the massage setting on that shower head instead of the regular setting is better for hydrobating.
