n. a high five preceded by a run up and a lunge. Usually connects with a meaty 'crack'. Can be accompanied by a manly grunt e.g. "HAUUUURGH!!!" or a "This is SPARTAAAAA!!!"
Guy 1: "This... is... SPARTAAA!!!"
*both guys run at each other, pull back and lunge into high five*
*CRACK! of hands*
Guy 2: "Fuckin' awesome Spartan five... Umm... I should probably go to the A&E, I think I may have broke something, erm... In a manly way... HAUUUUURGH!!!"
