Ah, found this old reference posted by Janice in NJ in one of the other threads. Not what I was thinking of, but still maybe fits the original category:

And in The Ball of Kerrymuir there are these lines:

Oh, the Ball, the Ball of Kerrymuir,
Where your wife and my wife were firkin on the floor.

Presumably they were firkin each other, although they simply could have been separately firkin other parties, male or female. The lesbian possibilities add to the humor.
