Ok, first off, I spelled it wrong. It is spelled Tellarite. Sorry about that.

A Tellartie is an alien, which has an appearance of a pig (that is NOT why I think PF is like them by the way. ) and is such a creature that likes to insult others. In fact they will be offended if you do not insult them back. Their first order of business after greetings is to find something to complain about. If they cannot find something to complain about they will just insult you and except you to insult them back. That’s a Tellarite in a nut shell.
