Stemming from the meme "No airbags we die like men", this term has been adopted by fanfiction authors, mainly on fandom website ao3, who use it to signal that their story hasn't been beta-read before posting and might therefore include a few overlooked spelling errors.
Variations of the term have been created for specific fandoms to match a fandom's inside jokes.
A foolish male who works long and hard to financially support a woman who, ultimately, does not love nor respect him and is not sexuallyattracted to him.
Ned was a idiot for being a beta provider for Becky and for thinking a woman like her ever loved him. She cheated on him and now he's stuck paying alimony, while she rides the alpha cock carousel.
It's a word that doesn't exist. If you're looking for this word from that deep English terminology phrase, good job on being inquisitive enough to try and understand what it means.
Me: I hate people who use deep English just to make us feel intoxicated by exuberance of verbosity betaprutal contraption.
Dummy: Word.
