This was a vulgar song commonly recited in country sarangbang.
The husband sucks above;
the wife sucks below.
Above and below are disparate,
but the flavor is the same.
The husband sucks two;
the wife sucks one.
Two and one are disparate,
but the flavor is the same.
The husband sucks the sweet;
the wife sucks the bitter.
Sweet and bitter are disparate,
but the flavor is the same.
