tank wank 

An abbreviation of the name for the practice of 'tantric wanking'. This is when one masturbates to the point of near ejaculation, but then suddenly removes his hand from his penis and proceeds to sit on it in a meditatory stance, thus ceasing the self-stimulation. The wanker repeats this process over the course of two to three days. Needless to say the result is incredibly spectacular, but can unfortunately result in knob-ache.

Boy 1: Where have you been for the past week?
Boy 2: I was having a tank wank
Boy 1: woah.

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!

When you see someone hot, you put their memory in your wank tank so that when you have a wank later it is the face you see as you cum all over your bed

Wank Tank

Testicles. So called because that is where the fluid that comes out when you ejaculate is stored.

I haven't had sex in weeks. My wank tank is ready to overflow.
