_sister_madly_ and I were playing Scrabble by rather "loose" rules. We didn't challenge too much and we allowed slang. As a result, she didn't challenge me when I played some words I wasn't sure of, but when she added an "f" to "unbags", I immediately challenged it. I wasn't trying to be a jerk and deny her that slang word. I had honestly never heard of "funbags". As it turns out, neither did the Scrabble dictionary. images.google.com, on the other hand, did return a few eyebrow raising results.
