Fishtailing 

Similar to a wedgie. The perpetrator sneaks up behind the victim and quickly inserts his fingers in between the victims ass cheeks, hitting the sensitive skin and putting tension on the victims cheeks and anus. If done correctly can be extremely painful, however should only be done in a joking manner among friends.

Mike: Damn I was walking in my living room yesterday, and Dana fucking fishtailed me so fucking hard.
Dave: Damn, that sucks dude. I hate Fishtailing

Fishtailing 

When girls who go to a uniform school roll their kilts wrong, the pleats at the back stick out.

Tawny: Man I was talking to Pete yesterday then I went to the bathroom and noticed I was fishtailing!
Olga: How embarrassing!

When it is late at night (around 3am) and your intoxicants have worn off, and you are just a shell wandering or staring aimlessly at walls, like a fish in a tank. Also, to actually fishtank you cannot be aware you are doing it -- that would mean you're coherent.

"We have to get Kevin home -- he's totally fishtanking."

Fishballing 

Fishballing is when you try to catch fish in a sink with your bare ass cheeks.

“Why the hell are there fish in my sink, John.” “Don’t worry Maggie; I’ll do some fishballing and get em’ out.”

Fishtanking 

When you are sitting back in a group setting or party and just observing what is happening and watching the drama unfold.

Do you want to get to the party later and do some fishtanking? I heard there might be some drama that goes down. Perfect opportunity for us to fishtank.
