About

A golf clap is a quiet form of clapping performed by lightly and rapidly clapping the fingers of one hand against the palm of the other. It is patterned after the sound of distant clapping heard during televised golf tournaments (during a golf tournament, a golf clap is an audience’s normal show of appreciation via clapping, but done quietly to not disturb people golfing at other nearby fairways, hence the intentionally subdued sound level).

The “golf clap” is employed as a sarcastic form of applause, used to show indifference or disdain, just as the ‘slow handclap’ may be used.
