runescape sex 

A yard-stick by which terrible sex is measured.

However some members of the Nerd and Geek Communities may have actual RuneScape sex. However noone actually admits to it outside of a joke.

I had sex with a big black sweaty black chick last night. It was almost as good as RuneScape Sex.
