“Open hole” or “Cased hole”, depending.
lieu, who worked cased hole in Pampa for Gearhart Owen, the GO(nad) Co.
Okay.
What did I just learn?
Peace,

I ride my chopper sometimes in a sorta pink cut off “T” , shorts & flip flops, just to see if anyone has the ‘nads’ to laugh in my face IRL. So far, no takers… < veg >
I think I’ll put a set on my computer.
If you hit loose gravel and need to plant both boots flat on the road, you’re going to do what? 
I hate you.
Gah, it looks like said truck caught the clap.
What next-truck penises? How about bumper boobs?
How about a tapeworm dangling from the tailpipe?
Hey, has that thing got a heme in it?
Where the hell’s my cookie? BAM BAM
Well, they do sell “car bras”. Just google that phrase and you’ll see tons of stuff.
Oddly enough, though, googling “car jock strap” doesn’t come up with any products at all.
Are you kidding, or what?
Who’d do a silly thing like that? 
Been there, done that, at least for the latter:
Aww, but nothing says “I am a patriot” like a flag-covered scrotum.
I wonder what the rabid anti-flag burner folks say about that.
Probably “Cool”.
You can’t really tell they’re nads from a far. Looks more like a bicycle seat. Hehe.
Those are the nads of the truck driver. When he’s not drunk he’ll realize what he gone an done.
I have finally seen a set of these on a Massachusetts truck. And I thought we had more taste than that, up here.
What’s needed, I guess, is the feminine equivalent – a plastic udder to hang under milady’s truck.
Actually that would more like a set of plastic ovaries.
But I’m not one to nit-pick. 
Anyway, most of us wouldn’t even know what we were looking at.
