The process of hitting on a girl you'd like to fuck, but can't because you have a girlfriend. This technique allows you to stay sharp when said relationship is terminated.

Sharping 

(verb) To mark the thigh of a woman during oral sex with a small mark or symbol using an indelible marker. Commonly done where the woman cannot easily see herself and meant to warn future partners that the woman has been "sharped" before.

Guy 1 "I was sharping that one chick, and I noticed your brand."
Guy 2 "Yeah, I went down on her. It looked like Jimmy and four other guys sharped her in the last few months too. Total skeez."
Guy 1 "Whore."
