For those that haven’t had the pleasure, these are truck nuts…

Truck Nuts

They are so named because they a) look like a male scrotum and b) because they are generally seen hanging from the back bumper of a pickup truck.

Truck Nuts.

I don’t get it, but some jamokes of the world apparently think that hanging a scrote for the viewing pleasure of the other drivers on the road implies toughness and virility.

Of course, it also implies a shortage of quality genetic material and a lack of education.
