How can I go about giving someone an std? I don't have anything, and don't know anyone with one. What are ways I can go about getting a hold on some...? I'm serious about this.
The guy passes out every weekend from drinking, and that'd be a perfect time to put it in.

just go downtown wherever you live and hire a hooker, after that when hes passed out, insert your peni into his anus.

Props for being evil but I implore you to reconsider. Unless they did something lifelong and permanent to you, you shouldn't be dishing it out. That's just fucked up.

Do something temporary on the same level of fucked up. People change. What if you became best friends in a couple years? I chill with someone I wanted to kill a couple years ago.

give him some std that he can cure. i always wondered how fun it'll be to give ass hole AIDs.

Try to find used syringes and hope you get lucky.

lol. +1 for "peni"

find a hooker with crabs, then get her to rub her crab infested snatch all over his crotch/hair/faicial hair etc. wont hurt him too bad, but itd be hilarious knowing that this guys using a tiny comb to go thru his hair pubes and beard all in one sitting

+1 if the crabs spread to his ass and taint hair

this is retarded.

Give him an STD thats cureable.

You're fucking pathetic. Your roomate fucked your girlfriend, and now you're trying to secretly give him an std? What are you, french?
