Short for Treated Burned and Served, TBS'd means to be put down or embarassed by someone; humiliated and "shut-up" without chance of comeback.

Taco Bell Stress Disorder. a disorder that only Taco Bell employees have. When you see XLG on a license plate, you think of the drink size. When you greet someone with "Hi, welcome to Taco Bell. My name's _____. How are you doing tonight?" it means you have TBSD.
