Hydramaticphobia 

The fear of automatic transmissions, or the premature failure of an automatic transmission.

Guy #1: Hey man, how's your new car? Did you get that new high tech automatic transmission option?

Guy #2 Nah man, I have Hydramaticphobia. The few cars I've owned that were automatic were nothing but trouble. I fear buying auto, so I'll stick to Manual transmissions no matter how hard they are to find these days.

Guy #1 : I hear ya.

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 1: Dude I just had a nice and long sonic hydrobating sesh

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

Hydrobat 

A hydrobat is an acrobat of the water. The king of fresh water hydrobatics is, of course, the manicly playful river otter. Salt water hydrobats include sea otters and sea lions, but dominance of the salty expanses is mostly reigned over by dolphins. The hydrobat has little competition from other animals and is able to spend a significant portion of the day honing its playful skills.

Q:How many flips can you do under water.
A: As many as want, I'm a hydrobat.

I am so jealous of hydrobats, they are always the life of the river party.
