halo sex 

bribing your girlfriend (or gay guy friend) to dress up like master chief before you give them anal sex. it works in other places as well but the asshole is best because it is universally available on all candidates. less common but equally effective costumes include: grunts, elites, warthogs (vehicle or animal), cortana (try this one with your guy friend :P), and flood (those things suck like you can't believe!!). playing halo at the same time adds to the experience (try that on legendary!!).

so lets say you are bisexual. you have your girlfriend and guy friend over for the night and you can't decide whether to play halo or do something strange involving sex. DO BOTH OF THEM YOU FUCKTARD!! have her dress as master chief, have him as cortana (or a warthog :P) and "cock and fire" in both halo and real life. you'll have so much fun, you will talk about your halo sex experience on the forums (and live) for months!!
