When one masterbates into their own hand and before proceeding to clean it off shakes another persons hand. Named such because of people spiting into their hand to get a better grip on a phillip's screw driver for example.
Andrew: "Dude what's this on my hand?"

Nick: " I think Dan gave you the Phillip grip."
