Fish Wank 

The act of one placing their hand into slimy, old fish tank water and proceeding to masturbate with the lubed up, fish tank hand.

"See that goldfish tank over there..."
"FISH WANK!"

Fish-Tank Wank

When a man gets sexually aroused and 'horny' so he masturbates and when he cums he lets his seaman fly into the fish tank, killing the fish, but resolving his sexual fustration.

I had a wank last night and didn't want a huge mess all over the carpet so I did it in the fish tank!

Shit, i appear to have killed my fish.

Fish-Tank Wank's are the best!
