I’ve seen this done a few times. Usually it’s a guy with a jacked up diesel. We call them flat billers around here. My F350 can “roll coal” if I really hammer it and push upper rpms but I don’t see any po8nt. My F250 is stock so it doesn’t do it at all even when full throttle it’s not noticeable. Either way I don’t care to do it even if I could. It’s pretty childish behavior

 

Flat billers? Like as in they bill a flat rate for work?

 

Lol. No. Sorry. Guys who wear baseball style caps but the bill is completely flat (no bends) and they usually leave the little holographic sticker on there. Sometimes wear them crooked off the front. The caps may have a F-word Monster Rockstar MMA or some dirt bike or some kewl of the day clothing manufacturer or some other bro type logo. I call them douche bags but for some reason it hasn’t caught on. I’m still crossing my fingers....

 

Oh I getcha. Dumb young punks, probably spoiled by their mama after dad left. And they roll coal for fun. I towed one's F-250 home for him the other day, made some hot shot bucks. He couldn't be bothered to clean the trash outa his cab or bed. I wore coveralls just to drive it up on my car hauler. His mama told me maybe he needs a nicer truck. I said make him clean this one up first, don't reward his lazy a** for being a slob. Were that my boy, I'd take the keys away.
