If you have VIP you should see a field in "Edit Options" in your UserCP that says something like remove Usertitle.
If you don't have VIP you can buy a Usertitle from the Market.
If you want to remove the Default Usertitle you can't,you can just buy a blank one. (Blank Usertitle Costs 42.5k For NON-Vip and 8k with VIP)
