spanktank

The reserve of sexual images or thoughts used for masturbation. Similar to a gas tank, but imaginary and naughty.

"Did you see that girl's tits?"
"Oh yeah! That's some definite fuel for the spanktank."

Spanktank

When you slowly and continuously fill a fish tank with your semen, take a microscope, and watch the dead sperms float around.

Tyler: Yo dude have you been filling your spanktank.

Vincent: Yeah mang it's filled to the brim with my little swimmers.
