bumper nuts 

Prosthetic testicles used to adorn the oversized vehicles of those who think very highly of themselves.

Jeff hung a pair of bumper nuts on his Tacoma.

He did take it off-road once, and ironically his ground clearance was insufficient to prevent a rock from removing a portion of his oil pan and wrenching the faux balls of his otherwise unused trailer hitch.
