Gmod is a modification of the source engine used to make several games, including Half Life 2. Some guy named Garry got bored one day, and probably thought he'd make a pimptacular game of all the nifty and fun things we loved most about Half Life. Since then, people have used his mod to create an ever-expanding archive of games and mini-mods to keep us glued to our computers at all hours of the day!

Fuck girlfriends and jobs, we have GMOD.
Gmod is short for Garry's Mod.
