Tuna can penis

A short, but very wide human penis. It is widely accepted that one does not have intercourse with a tuna can penis, but rather uses it to punch their lover in the cunt.

Shelly: "I heard Mike has a thick dick. I am so jealous you hooked up with him!"

Nelly: "Umm, we didn't hook up so much as he punched me in the cunt with his tuna can penis"

Shelly: "gross."
