Ballfish 

The extreme fishy smell a man's balls and penis produces when not cleaned properly overly an extended period of time. Though many complain of a "woman's smell" ballfish is truly the worst. Some groups of men will yell out BALLFISH loudly when they smell it .

Once I removed my boxers, it was evident- I had ballfish in the worst way and had to shower.

A completely different Bullfish 

The expression is used to discribe a ”Different Kettle Of Fish” and a “Whole New Ballgame”. First used by Greg Western in 2017, combining the two sayings into one hybrid.

billfish

A breed of fish indigienous to Honors Hall. Can find this creature either playing Overwatch or listening to Azizi Gibson. Most Billfish have one friend that has a Y in their name and a freesytler named Benny Bills. Overall pretty solid swimmer unless their is a fire hydrant near by for said fish to smoke their “knee” on.

“Yo what up Billfish”
Billfish: “fuck off”

bullfish 

1) A fish with bullhorns. Usually summoned from the sky by a Bullfish Summoner, but can fall down from the sky on it's own. Can be found in waters too. Beware of this unfriendly fish. They smell bad, don't taste too well and can pierce you with ease. Don't drink from natural bodies of water.
2) A substitute for the other BS.

1) I hope bullfish fall from the sky and stab you through the head.
2) This is bullfish!
