Deputies have arrested a man accused of suffocating his stepfather with his own underwear and striking him in the head in McLoud, Okla.

Brad Davis, 33, was arrested Tuesday night after he reportedly told Pottawatomie Sheriff’s investigators he had given his stepfather an “atomic wedgie,” NewsOk reports.

For those who don’t know, a wedgie occurs when someone lifts someone’s undergarments so that they become “wedged” between their buttocks. An atomic wedgie is similar, but goes one step further by lifting a person’s undergarments over their head.

The victim, 58-year-old Denver Lee St. Clair, had died on Dec. 21 from blunt force trauma to the head and asphyxiation. The state medical examiner ruled the death a homicide.
