JACKSONVILLE, N.C. — At a junior officer sleepover party over the weekend, fellow partygoers dared Marine 2nd. Lt. Dustin McBride to go into the bathroom with the lights off and chant “sergeant major” in the mirror three times, sources say.

“I’m not afraid of Sergeant Major!” McBride reportedly said before the other lieutenants closed the bathroom door behind him. “I outrank him!”

Witnesses said the sleepover party was playing truth or dare prior to the incident. At first, McBride chose truth, but he quickly switched to dare after the other lieutenants asked if his Marines respected him.
