A romantic fast food lunch quickly took a turn for the Maury after one cheating dad found himself confronted by his son while treating his alleged mistress to a steamy afternoon at their local rest stop.

“Run around on my mom like that? f— you,” the son screamed at his dad, who appeared to be chowing down at a Subway/Chicken shop in Baird, Texas.

Though an employee quickly intervened after he hurled the c-word at his father’s new woman, attempting to shoo the seething son off the premises — “you need to leave!” she exclaimed, moments into his tirade — he refused to budge, continuing his diatribe against his two-timing dad.

“No, my dad is running around on my mom and I’m about to clean his f—king clock!” he shouted at the worker.

“I’m not running around!” the dad fired back, alleging that they were just out there to “talk,” an excuse his son was apparently having none of.

“Aw bull f—king s—t!” he continued threatening to take “both” of those “motherf—kers outside.”

Though he didn’t make good on his promise, several TikTokers apparently wished he did, flocking to the comments of the viral clip to praise him for so adamantly defending his mother.

“He and Romper Stomper have been nominated for the Best Kid of the Year award,” commented @lesa.kistler, referencing the woman who protected her mom during the now infamous Porta Potty beatdown at a recent Morgan Wallen concert. “Both win in my book.”

“These young adults defending their mothers is the best!!” added @absolute.heart, while @crystalevans08 encouraged the son in question to make good on his threats and actually “clean his clock.”

So take it from this son — Heck hath no fury like a protective son scorned.
