Definition

Short for Boring Status Update: a post so dull it deserves its own acronym, like 'is typing...', 'is bored', or a lonely period. It's a Facebook classic, where users treat their feed like a live broadcast of their nap schedule. The standard reply is 'enough with the bsu,' the internet's polite way of saying put the phone down.

Example Usage

Another 'is eating toast' post? Come on, that's a textbook bsu.
