Pens trails? Panster lulz? Pan steer lies? Pins TRL Z? Like a Total Request Live reference? Pines tour reals? No, probably not...puns trials? Pains too...reals? That would be kind of deep, right? Punster lies? Pans tear roles? Panster rolls? Is that a thing? That sort sounds like it could be brand of dinner roll. Pines...tar...riles?
Oh, it's probably "Penis trolls." Yeah, that's a pretty good license plate. "Penis trolls." Ha ha.
