My wife's niece (technically not blood to me) was a little kid when we got married. Well, in reality she's as much blood to me as my brother's kid. Years ago, when she was in her 20s she came to a beach event wearing a thong suit. I was so embarrassed I couldn't look in her direction that day. She is a very sweet girl, had no idea. So many women were wearing them at that time.

I know those are supposed to be sexy, but all I can think about when I see one is "wedgie".
