A slapping of the nutsack.
I'd like to bagtag Leonardo De caprio, cause he's an assmonger.
To hit one in the chin with a pair of testicles. One step up from the "T-Bag", and with a more hazerdous outcome to the victim. Often leaving a bruise on the chin. Followed by an echoing "pung" sound.
Sally wouldn't give it up so I had to Bagtag that chin.
