It probably is an emote. You're post is a little sloppy though, so it is hard to tell what you are saying.
To use an emote though, type /sit or /laugh or /wave in the chat box. If you need to use the bellow emote, type /bellow.
You're best bet if you are playing on a ps3, is to buy a cheap usb keyboard to plug in to it, so you don't have as many problems with emotes or communicating with other players in-game.
