Wife-Beater 

In the UK, originally the white string-vest, but most vests/tank tops get reffered to as Wife-Beaters.
The oniginal example was so called due to the fact that the main type of person who wears string-vests was usually a fat, wife-beating, alchoholic.

...look at that fat man in that wife-beater...

a very tight, white tank top that is ribbed in texture. this style of shirt is usually found on overweight white guys hailing from the trailer courts. unmistakeable markings of bbq sauce or chew spit on the front and smelling of old style beer and excessive perspiration. the wearer can be found at any type of festival which involves his toothless relatives working the carnival rides.
