form fitting white ribbed tank top worn by men; looks good on well-built fellas, pathetic on skinny fellas, and disgusting on fat beer bellied fellas

"Bi wife energy" is a term that was coined through a song by the user @/cringelizard on Tik Tok to describe the energy that Misha Collins radiates, explaining it with the fact that he is married to a bisexual woman, Victoria Vantoch. The full song can be found on all music streaming services and YouTube.

People with bi wife energy are fiercely supportive of the LGBTQ+ community, their love for their spouse, if they have one, is strong and people sometimes assume they are queer.

In their first video about this, @/cringelizard referred to Misha as a "hetero guy", but amended in a later added verse that the actor does not like labels.

The term "bi wife energy" can be used for people of all genders, regardless of relationship status, although "bi husband energy" has also been used in several videos across Tik Tok.

Lyric excerpt:

(Verse 2)
Now sometimes people assume I'm queer
And I have to say, hey! just a straight guy here
But I get it a lot, and I don't mean to be cruel
It's just that my wife is a bisexual

(Chorus)
Bi wife energy
He has bi wife energy
BI wife energy (yeah)
He has bi wife energy

A men's sleeveless undershirt.

I think the TV show "COPS" had a lot do with the creation of this word. Every time they showed a guy getting arrested for beating his wife he was wearing one of those sleeveless undershirts.

A tank top usually white

A white sleaveles t-shirt also referred to as a muscle shirt or singlet.

1. Men's close fitting, ribbed, sleeveless white cotton undershirt most commonly used before T-shirts came into vogue as undergarments. It is named wife beater after Marlon Brando's character, Stanley Kowalski, who wore one during much of the movie version of Tennessee Williams' "A Streetcar Named Desire." Stanley proved to be a sloppy, drunken, ill-tempered brute who beat his wife.
2. Slang name in Britain for a Belgian lager, Stella Artois, mostly because of the name, Stella, after Stella Kowalski, the victim of a beating from her husband, Stanley, in the aforementioned Tennessee Williams' play, "A Streetcar Named Desire," but also because of the high alcohol content which could possibly lead one to wife beating were he so pre-disposed.

In the UK, originally the white string-vest, but most vests/tank tops get reffered to as Wife-Beaters.
The oniginal example was so called due to the fact that the main type of person who wears string-vests was usually a fat, wife-beating, alchoholic.
