To make friends with a girl and gradually convince her to break up with her boyfriend for you, thereby “stealing” her.
Hey man, can I talk to you? “Sure” Well, it’s just.. my girlfriend has been less intimate towards me.. I dunno why.. she’s also spending a lot of time with this dude.. Going to the cinema with him.. hanging out.. you know? “Dude, I think you totally just got Mark Ray’d”
