This is an extremely enjoyable sexual act where one person is doing their partner (male or female) in the ass with extreme aggression and perhaps even reckless abandon. Just before the fucker climaxes they pull out and proceed to beat the fuckee to death with a putter, preferably with a Williams Limited Release 24K Gold Plated Putter purchased from one's local Dicks Sporting Goods Store.
Guy 1: Dude are you alright? You look like you had a rough night!
Guy 2: Yeah man, but just barely. I managed to survive and attempted Magic Putter. No more LSD for me....
