The joke was a complete flop,' she said.

It's just been four days since TikTok's video of a motorist "rolling coal" into a Whataburger dining room went viral, racking up more than 910,000 views.

A huge cloud of exhaust can be seen coming through the restaurant's entrance while customers in the dining area stare out. If you're not familiar, "rolling coal" refers to the technique of increasing the quantity of fuel put into a diesel truck's engine to produce uncombusted diesel fuel, which is then pushed into the atmosphere and darkens the exhaust's appearance..

@jaysonmanzanares0's TikTok video on the dangers of pumping exhaust into a confined space has received 1,434 comments.

"Doesn't it sound a lot like a murder attempt?" In the comments, there was a post from trevonburrellofficial.

One reader wrote: "Some guy pranked his buddy like this by burning his vehicle while he was sleeping in it and he died from carbon monoxide fumes.

Others used the occasion to make a joke about the eerie aspect of the exhaust cloud.

One commenter described the occurrence as "bruh I believed a ghost unlocked the door and stepped in."

Texans, where the fast food joint is located, have been hearing a lot about rolling coal lately. However, there are no laws against rolling coal such that it comes into touch with spectators in Texas, according to a district attorney there. The DA was referring to an incident in which a teenage motorist allegedly threw coal at and then struck six bicycles in Waller County, Texas, resulting in the need for emergency airlifts for two of the injured bikers.
