May 26 Word of the Day
"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
"You know Misha Collins?" "You're talking about that actor, right? The one that radiates bi wife energy?"

"Amy Santiago has so much bi wife (bi husband) energy!"
