ELI5:Why do they call the sleeveless shirt wife beater a wife beater?
gpt
It is, like many other things, based on a semi-humerous stereotype. 

From another site...

> ... in 1947 in Detroit, Michigan — when police arrested a local man (James Hartford, Jr.) for beating his wife to death. Local news stations aired the arrest and elements of the case for months after — constantly showing a picture of Hartford, Jr. when he was arrested — wearing a dirty tank top with baked bean stains on it…and constantly referring to him as “the” wife beater.

> From there, everything snowballed. From then on, men wearing dirty tank-topped undershirts were referred to as people who were “wearing wife-beaters” and the lexicon stuck from that point forward.
