I think you probably mean Bonnie Green Garters, which is a traditional "dancing-off" dance. A lot of mens teams used to sing words to it usually finishing up something like "Off with her knickers and off with her bells and away with her bonny green garters" The womens team I danced with in York in the early 80's, Acorn Morris, used to sing "here's to the fellas as ugly as hell, and its hard to stifle our laughter, They whisper sweet nothings and jingle their bells, But we know what they're bloody well after. Oddly enough, some of the mens teams didn't see the funny side of it!
