Slaanesh is the chaos god of pleasure, passion, and decadence. To narrow that down to just 'oh porn lol' is a bit of a stretch.
well, it is a kind of pleasure and slaanesh is the god of pleasure... and it is funny to call people pervets cause you like slaanesh
I'm fine with all of the chaos gods myself. They all are equal in my eyes. Except for Khorne. He and his dim-witted berserkers can suck my blastmaster.
