Uh, don't really like to hear/read people talking about inflicting violence upon their spouse, even if the phrase is meant to be a "funny" way of referring to an undershirt. Why WOULDN'T I object?
Again, I'm 
clearly
coming at this from a completely different place in my head than, apparently, everybody else here, [unnecessary, deleted, sorry]
	
 
		
		
I thought they were called muscle shirts before "wife beater" took precedence.
	
 
		
		
 Before they were wife beaters, they were dago tees. 
We cheerfully called them Guinea Tees when and where I was a kid -- until it occurred to me what in the HELL I was saying. And then I stopped because it was awful. And I pointed out to my friends that it was awful. And eventually that name seemed to go away.
I just don't see much of that reaction to "tramp stamp". (Well
now
I do :)
	
 
		
		
so I will shut the hell up and go the hell away
2 separate thoughts, and the second is never desirable.
	
 
		
		
The shirt in question is my preferred sleep-wear and I wish it had a better name.  One time we had a sleep over and three of us gals were wearing them.  A guy said, "when I die and go to heaven, all the women will wear those shirts."
	
 
		
		
I guess I got a little defensive about this because I do occasionally use the term, and when I do use it, I usually mean it to be derogatory, and I don't feel particularly apologetic for that. 
	
 
		
		
I don't feel particularly apologetic for that. 
Never apologize for using the phrase in a derogatory fashion.  I think we're just analyzing why that particular phrase and usage.

Yeah, that's why I realized it wasn't really an attack on ME, and I didn't at all need to shut the hell up or go the hell away.
	
 
		
		
I think wife beaters are usually white.  I like the black ones.  Remember in the 80s we wore two in day glo colors?  Were we calling those dago tees?
