The act of a naked man slowly getting up off his leather sofa and gently peeling his sweaty scrotum from the said sofa.
The wife n kids were away last nite so I spent all evening bag peeling... EPIC..!!!!
The act of unsticking of your scrotal sack from your inner thigh... usually during hot weather..
"Why are you grabbing at your groin like that Mike?"..
"Oh it's nothing, just a bit of bag peel.."
