— A dangerous viral game has turned deadly as a participant accidentally shot and killed their opponent in Memphis, Tenn.

The viral game known as the ‘No Lackin’ Challenge” involved two people who are instructed to film themselves pulling guns on each other without pulling the trigger.

Police said Sherman Lackland, 21, forgot the rules and pulled the trigger, fatally shooting the other participant.

The 17-year-old victim was shot in the head while seated in a Memphis café early Thursday morning.

Lackland was charged with aggravated assault, reckless endangerment and unlawful possession of a weapon.
