The Romans performed the first documenting mooning

During Passover, soldiers of the Roman Army were sent to stand outside of Jerusalem to ensure that nobody tried to revolt against the empire. This is where the first documentation of mooning occurred. A Jewish priest, Flavius Josephus, recorded that a Roman soldier had lifted “up the back of his garments, turned his face away, and with his bottom to them, crouched in a shameless way and released at them a foul-smelling sound where they were offering sacrifice.”

That didn’t sit well with the Jews. They started throwing rocks at the Romans, which eventually broke out into a full on riot.
