Betafish 

a person who is small in stature, weighs under 120lbs, has little to no muscle, and tends to have a very well below average sized penis. These people are typically of adult age but are seldomly referred to as men. You can find them wearing boys’ sized clothes because any men’s clothing would be swimming on their tiny frame. Their attitude is often extremely aggressive and nasty but they will never look you directly in the eyes when confronting you due to their cowardly traits. They will often only speak to women they find attractive and will either lash out at or refuse to acknowledge any men who speak to or pose a potential threat to have sex with the woman they are simping over. It is not uncommon to find these pathetic creatures whispering to a woman for absolutely no reason at all while the woman speaks using a normal tone of voice during the conversation. You may run into these pathetic weaklings verbally degrading the nicest humans they encounter just because they see an easy target. The most entertaining aspect is when they argue adamantly with someone but are proven wrong time and time again with their only response being “whatever.” In some rare cases they will be a third wheel and pay the entire bill. There unfortunately tends to be a high rate of domestic violence and verbal abuse cases due to their inability to challenge any grown men in the public sphere.

Note: Bettafish is another common spelling. Fish is often used as a shorter slang term.

Mike: “Yeah he’s such a betafish!”
