The act of an individual giving a handjob using two hands while interlocking the pointer finger of one hand and the pinky finger of the other creating the same grip used when swinging a golf club.
"Everett bro you won't believe it but that girl I meet at that party last night that only had nine fingers gave me a fat Golf Grip Handjob."
"She locked her left hand pointer finger and right hand pinky finger together and started tuggin' my meat... She used the Golf Grip brotha."
