Originating in Central KY, 'sfepp' is slang word for casually fondling, feeling up, playing around with, squeezing (lightly) a friend or aqquaintance's genitals or breasts. It is most commonly used among horny teenagers and groups of younger adults to describe the non-sexual yet still arousing general flirty-touching among friends of opposite and same sexes.
Emily- I walked up behind Jas in the hallway and sfepped him while he was putting his books in his locker, you should have seen the look on his face!
Molly- We should play *sfepp* coin, heads, i sfepp you, tails, you sfepp me (played on long school schoolbus rides)
Joe- We were bored and tired on the way back from Texas, so Jesse and I sfepped each other... no big deal, just casual goofing around and teasing ;)
A word to describe the act of being horny at school, or in a social situation, usually to the point of genital arousal (nipples, boner), etc.
