As if the "Left 4 Dead" Valentines weren't nerdy and amusing enough for me, some endeavoring individual has gone through the trouble of filling the San Fransisco Bay Area Craigslist with not 1, not 5, but 11 "Left 4 Dead" themed casual encounter postings (still active as of 9:10 EST). For those not familiar with the concept of casual encounters on Craigslist, it's basically a forum for sociopaths to set up anonymous booty calls and various sexual shenanigans, and a boundless source of creepy comic relief to your average well adjusted citizen.
Out of the bunch, my favorite is the smoker post, because with a title like "LET ME WRAP MY LONG TONGUE AROUND YOU (L4D)", it appears very much like your run of the mill casual encounter. Enclosed in the post is another cryptic mumbling that should be readily recognizable to fans of the game:
SMOKER! SMOKER!!!!! Smoker over here.
According to Kotaku, the Smoker post was convincing enough to warrant a reply, and boy, either they are in on the joke or it's about to get REAL awkward.
