A straight arm closed fist over the head strike of power in which you boink someone right on top of da dome piece while running towards them. A new type of street fighting in which you just start boinking niggas on top da head and taking all their monies when da end up in comas. The most successful Nordic Hammers are also very good at Whack-A-Mole.
Yo, I was at a party the other night and a fight broke out. Then this nigga came out of nowhere and started dropping Nordic Hammers on everyone.......even girls and babies they all in comas with crushed skulls.
