Enema
Enema (also known as Enema Los Santos ) is a clothing company in Grand Theft Auto IV and Grand Theft Auto V. The brand is named after an Enema which is like a play on the idea of being thin in fashion (as Enemas can be used for the purpose of shedding excess weight) similar to other brands such as BULL EMIC, Anna Rex and Sizero.
An Enema billboard can be seen in the trailer for GTA V.
