A condition occurring mostly in (although not limited to) uncircumcised men as a result of not cleaning their genitals, particularly under their foreskin. Their lack of concern for personal hygiene results in their genitals producing a nasty fish smell. 90% of men with this condition will request oral sex while remaining oblivious to the fact that they have it.
That guy I hooked up with had a MAJOR case of fish dick.

A nasty rotten fish odor that tends to occur when a guy masturbates too much. Semen drys up on penis after he is done which smells like rotten fish.

What the human male experiences after a night of unprotected sex with a woman then leaves in the morning without showering, and follows that with a day of hard work in a hot kitchen. It is a combination of a foetid stench, grease, slime and crusty scaliness in the genital region.

A joke involving a play on words in a South Park episode, because really... if you like putting fishsticks in your mouth, you're a gay fish!

Kanye West: Yeah
Everyone: Do you like putting fishdicks in your mouth?
Kanye West: Yeah

A male-identifying person who's display of over-compensation is so outrageous, they may as well have a genital papilla instead of a penis.
