A penis with a strong fishy odor from intercourse with a female who doesn't keep her vagina clean.
The people involved with
the intercourse in question are the only ones who don't notice the stink.
Most anybody else within five yards or so will smell it and be physically sick.
Short of amputation, the only way it can be cured is to
soak and scrub the area with a strong pine
disinfectant.
Chuck: Did you fuck that
skanky bitch?
Willy: Sure did, and it was good.
Chuck: Eeugh! Moby dick, man!
Willy: Shitshitshitshitshitshitshit.
