What is Plum Bag?
1.
The often goose-bumped, sometimes reticulated, sack o’ skin suspending the testes at a controllable distance from the groin so as to maintain temperature equilibrium, because the little spermatozoa inside don’ like bein’ too hot or too chilly.
“If you don’t do what I tell you right now, your plum bag will be my hacky sack.” -- Vanessa Marcil as Samantha Jane on Las Vegas episode “Run, Cooper, Run”
