GBD

An acronym for " Gang Bang Day", GBD is a term used to describe a busy or full day where there is one thing right after another, nonstop.

Person1: Man, I had the busiest day: I worked a full shift, went bike riding right after work, then had just enough time to shower quickly and catch a movie with friends all before getting a late dinner.

Person2: Wow, sounds like a GBD to me.
