Hitting on your friends wives, girlfriends, etc.. In a non-threatening, back door way. Using your friendship as a gate way to grope, fondle, talk dirty too, using a DJ voice to bad mouth you to your girl to make himself look better even front of his fiance B. Also, but not limited to strangers, young girls, and feet.
Seduction includes stress ring that doubles as a wedding band.
