"Gay Chub" is a category in the adult entertainment industry that refers to content featuring gay male pornography, specifically focusing on performers with a "chubby" or larger body type. The term "Chub" refers to individuals who may have more body mass or a fuller figure than traditional standards of attractiveness might suggest.
In this context, the tag "Gay Chub" is meant to indicate content that appeals to those interested in seeing attractive, chubby men engaged in sexual activities with other men. This category often includes performers who may not fit the traditional muscle-bound or slim body types commonly associated with gay pornography, but are still considered attractive and desirable by certain viewers.
