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.
