Short for Fuck Bitches Get Money, which in general means that one should not bother in the futalities of chasing women when money can never let one down. However, FBGM is quite versitile and can have several different uses. Among the most popular is to soothe a fellow "FBGMer" if he has had a bad day, synonymous with "fuck that shit," and can even be a reply to simple questions such as "what's up?"
