A honeyburger is a young woman who is 50 to 100 pounds overweight, yet carries herself in very well. She dresses fashionably (often in animal print), smells good, accentuates her positive features, loves sex and fellatio, and has a great personality. She'd be hot, if only... she weren't a honeyburger.
n. or adj. A middle-aged man whose prime has long passed, and is in denial that the glory days ever ended. Particularly applies to ex-jocks who now work as ineffective high school math or science teachers just so they can coach football and flirt inappropriately with cheerleaders.
