Okay, I tried it:
You're now chatting with a random stranger. Say hi!
Stranger: how r u?
You: I'm pretty decent. I'm testing my theory that only people who want sex chat come here. What's your motive?
Stranger: also,but i'm interested in other people
Stranger: just when i'm horny i'm looking for sex;)
You: Cool. I'm a nerd but I get enough sex, so I only chat to vent rage or to have goofy conversations
Stranger: yeah,something like that
You: I vote for goofy
Stranger: i vote for sex
You: goofy sex?
Stranger: no,just sex
Stranger: drunk sex
