Inspired by the feeling one gets when intoxicated, Gnomes have created beer goggles. The euphemism was coined after going home with too many questionable partners after drinking too much. Beer goggles, however, are actual goggles with smoky brown lenses and brass and leather frames. They fit tightly on the face and are made for all sizes, but 70% of them are small. Beer goggles give the wearer the ability to create an illusion to disguise themselves.
In World of Warcraft, "Beer Goggles" is the buff received by wearing or which can be bought at Brewfest.
