Other forms: groaned; groans; groaning
A groan is a sound of pain or disapproval that doesn't consist of words, usually heard after homework is assigned or bad jokes are told.
People groan for lots of reasons: headaches, stomachaches, traffic jams, and bad news are just a few groan-worthy things that can provoke that moaning, "uuugghhhhh" sound. If someone is complaining about something, you could say she's "moaning and groaning." People like to moan and groan about the weather, politics, and just about everything else.
