Definition #2 A "Fender Lizard" is one who can be found crawling under fenders admiring the suspension of that particular vehicle. Very popular in the Off Road Community especially as the vehicles line up for inspection or at the start line.
A dude with a flatbill hat and black socks with his head stuck between a tire and fender of a Trophy Truck may be refered to as a "Fender Lizard". He may even take a picture on his cell phone of the impressive suspension to send his fellow flatbillers back home...
