...Another way is to of coarse do the complete opposite of trash talking them. This is perhaps the most fun way to go about doing this, since you can almost never run out of things to say.
Choose ONE of these:
1. Pretend to fall in love with his mom (or other relative, such as his sister, or even his brother; if you choose brother, see #2). Ask for her picture at first, be very nice about it, so he actually believes you're asking for it cause you really like her. Ask about her breast size, the color clothes she likes to wear, whether or not she likes <insert sexual position here>. Then ask where she lives, and for her phone number. Get really creative and this will be very fun, and effective.
2. Pretend you're homosexual. I'm sure I don't need to tell you about how would go about doing this, but you should really get into it, to make it believable. Ask him to send you his pic once you've got him believing you're homosexual. Careful about this, though, because he may just start laughing at you and it may not work. Act as intellectually as possible towards his normally rude remarks.
3. Act like an annoying newbie. Put him on your friends list and enter whatever games he makes. Constantly spam him (not too much, cause he can just spam you back) with "do u hav free botd????!??!" or something of that sort. I personally hate begging, but when you're doing it not because you really want the item(s), it can be quite fun. Besides asking for items, you can also spam him with questions, such as "how do you tele with a barb?!?!?" or "how do you ww with a sorc?????????????????????!!!!!". If you work on this a lot, he may just give you a BotD to shut you up. :lol:
There are many other ways to go about doing this. Get creative. :thumbsup:
