BSTL

abbv. for "Bam Said The Lady". Commonly used by actor Nathan Fillion whenever he Tweets, since typing "Bam Said The Lady" can be a waste when you're limited to 140 characters.

"A reminder to Negative Nancys out there- keep it positive. It's insecure to think you have to be mean to be funny. Mean = blocked. BSTL."

Person B: BSTL!
