A sexual role playing game where participants dress as Halo characters. Male participants (dressed as Spartans) are punched in the prostate to induce internal bleeding, then ejaculate blood onto the other participants and yell, "Lasa LASAAAAH!!!"
"I got a head shot with my Spartan Laser last night... she's blind now."
