Humorous mismangulation of "gin and tonic". The term indicates a high degree of drunkenness followed by sex with a woman. It seems to specifically imply a man who is highly drunk performing oral sex on a woman. The tonic may, or may not be drank while performing the oral sex.
Damn, I wondered where Frank went at the party, so I walked out to the porch. He was so damn drunk out there with some chick on the porch swing. She was moaning out loud as he was getting some quim and tonic.
