horny? Gk for better orgasm

Gk is contraceptive

I thought her pussy was tight but when I insisted GK style... anal sex is a THOUSAND times more fucking awesome

Gk, as long as the position you fuck her in has her ass BELOW her pussy, anal sex is contraceptive (and not abortifacient like pussy on birth control)

Gk on the phone or cyber with her

Gk and jerk off to the sex video you shot with your girlfriend

The better your refractory period the more awesome Gk

If your girlfriend won't let you Gk in her ass dump her.

If a girlfriend refuses to Gk do a fucking video dump her.

An online gaming clan that originated in 1998 in dark dusty basements in the Pacific Northwest (USA). The clan originally played Rainbow Six, but has since moved on to Battlefield 1942 and the subsequent releases and Mods. Many perpetrate to be GK, in fact many have stolen the name in hopes of contracting some of the skills possessed by the founding father. A clan in Europe has even made a website calling themselves GK. There is only one true GK!

The original founding fathers included:
GK_SWooP, GK_joneZr, GK_Slick, GK_Nooch, GK_Money$hot, and GK_Wheelsofsteel.

The meaning of GK is a secret held by the clan members themselves.

GK's have sworn oath to kill all smacktards.

Short for Game Killer. A similar, more masculine form of co*k-block, a GK waits until things are going well and proceeds to irreversibly destroy a friend's ability to get ass. This is usually achieved by trying so hard that it makes everyone uncomfortable.
I was making serious headway with a Bulgarian (I think) skinny blonde with a ginormous rack when GK suddenly appears in my peripheral. After thirty seconds awkward conversation and bad jokes, the blonde leaves.
