Green Chile, Chicken Burritos: The Silent Killer

Sometimes the things that come out of my mouth while I'm drinking at the bar are funny at the time, but after sobering up they become disturbing and creepy. With that in mind, I will not be discussing my ill-conceived science experiment of infecting a green chile, chicken burrito with AIDS. Not only is it a terrible idea, I also don't know anyone with AIDS. (If you have AIDS or are willing to be infected by a burrito, email me)
On the subject of creepy and disturbing, lately Justin and I have been trolling the Craigslist personals. The "casual encounters" section, in particular, offers a steady stream of laughs, gasps and cries of "What the fuck?" On this day, however, I found myself lurking in the "casual encounters" section without Justin and the whole experienced changed (keep in mind that I am at work). Instead of a semi-innocent good time had with a coworker, it seemed more like trying to find free porn on my parents' computer (not that I ever did that or know what it feels like).
This isn't entirely my fault, though. Not with steamy passages like this:

I want to meet people who like to masturbate in front of me while I masturbate. I love to see young guys shoot their load right in the air...mmmmm.I am in bikini shape, i have strawberry blonde hair and green eyes. I can almost always make plans to host with a few days notice.

This personal confuses me in a few ways:

• What kind of a person makes themself that available on the internet?
• What does she mean by "host"?
• ...I don't even know what to begin with the "shoot their load right in the air" part.

Then, elsewhere on Craigslist, there are the whole "mw4w" and "m4t" parts that I can't begin to understand, hence I won't discuss them.
Maybe (read: probably) I'm really naive or immature, but this stuff facinates me. Like a science experiment.
I wonder if anyone on Craigslist would be interested in infecting a green chile, chicken burrito with AIDS.
