(known also as BBLunder)
When a person comes online purely to inform you that they'll "brb" or even worse, "bbl".

Sometimes they will appear like they are staying, but their just a little slow at that current time.

Severe cases of brburdens and bblunders are when the person or thing does not return.

This is classified as anIM-ocrite.
