origninates from the popular english initialism 'WAGS' which means 'Wives and girlfriends' These are the ho's who are seen on the arms of famous sportsmen. Similiary, 'glags' is a blend of 'glamorous' and 'slags' and is used to descirbe the women accompanying popular rap stars. One simply has to watch MTV for a few minutes to see evidence of very attractive women, dressed in only the best attire, but acting very unrespectable indeed.
person one : 'wow, i just watched an Usher video. there was this totally hot babe in there, dressed in seemingly thousands of dollars worth of bling and looking truly stunning. However, she was spreading her legs and acting like nothing more than a common prostitute. What MUST her father think?'

person two : 'im hearing you man, shes just another one of the glags that rap guys need to enhance their fucktard egos'
