Well, you get an A for effort that's for sure.

You're another one that it's tough for me to truly expound on what you can do better because it's tough to describe. I honestly think you have a very good foundation to build from, and you put forth a lot of work in that series with Sarah (who, BTW is one of our best trash talkers at present so I wouldn't be too upset about the loss). The best I can say is that some of your barbs landed and some seemed kinda ho-hum. My best advice would be to try to avoid cliche's (if you've heard it said a bunch of times before, it's probably not all that effective). The thing that wins trash talk battles is the ability to be witty, biting, and innovative. Using unique turns of phrase or truly nailing somebody on a character weakness is the way to go.

Like I said, I think you have a good foundation, just try to cut out the more well worn insults and I think you'll do well.
