SHDN = Shaved Head Douche Nozzle....a man who doesn't work, needs bailing out, a motorcycle, rims, a cell phone, bail and/or needs to pay back child support, gets all the funds from a desperate, dumb woman with exceedingly bad taste and then claims it was a gift.
The SHDN told Judge Judy that his gf bought him the truck and he didn't ask for it and he didn't need to pay her back.
