Not McGuilty was the verdict from a US judge who acquitted a young man of disorderly conduct for rapping an order at a McDonald's restaurant.

Spenser Dauwalder was cited with the infraction in October after he and three younger friends imitated a rap from a popular YouTube video that begins: "I need a double cheeseburger and hold the lettuce."

The 18-year-old said employees told them that they were holding up the queue and needed to order or leave.

But Mr Dauwalder said no one else was in the queue and the four left without buying anything.

A manager at the Utah outlet wrote down the car's licence plate number and called authorities. Officers later cited the would-be rappers in a high school parking lot outside a volleyball match.
