The sexual act of inserting the tip of a strap-on dildo into the foreskin of another penis.
It allows one to enjoy the sensual pleasures of docking while remaining in the confines of heterosexual relations, and can be used as an alternative to pegging.
Tom: Hey Mary, I'm getting a bit bored of taking it up the ass, but I don't like the idea of a man sticking his penis into my foreskin, so I thought we'd spice it up tonight with some grapneling.
Mary: That sounds great, dear! I'll get my strap-on!
