1. One that bends: a bender of iron bars; a bender of the truth.
2. Slang. An expression used to imply a binge drinking spree, referring to the act of bending over to vomit. Also used to suggest a binge drug spree—i.e. large use of cocaine or heroin in a short amount of time. Typically results in loss of memory and money, waking up next to strangers or with strange injuries, and other acts of foolishness you’ll have a hell of a time explaining.
