1. To kick the gong: To smoke opium (from Chinese opium dens of the last century where
customers struck a gong to make the
attendant come and bring them a pipe).
2. To
mastubate (if you're male).
1. Lyrics from "Minnie The Moocher" (30's jazz hit for Cab Calloway):
She messed around with a bloke named Smokie
She loved him though he was cokey
He took her down to Chinatown
And showed her how to kick the gong around
2. She gave me
such a case of
blue balls last night I couldn't wait to get home to kick the gong.
