Why do they call those white tank tops men wear "wife beaters"?
Because on so many cop shows, the actual wife beaters have those kind of tee shirts on.
Because old fat drunk guys wore them and they would beat their wives after work when they got wasted! In old movies and stuff! what Girliegirl2012 said is definitely kinda true as well!
If you grew up in the 80's men would wear cut off jean shorts wear the wife beater and drink Budweiser and smoke Marlboro reds and smack around their wives.
