A 33-year-old Oklahoma man has been charged with killing his stepfather by giving him an "atomic wedgie', one that caused the victim to suffocate on his own underwear.
He pleaded guilty on Monday to first degree manslaughter.
Brad Lee Davis was charged with the murder of 58-year-old Denver St Clair in a drunken family fight at a house in Oklahoma City in 2013, the Pottawatomie County Sheriff's Office said in an arrest affidavit.
The affidavit said he "grabbed St Clair's underwear and gave him an 'atomic wedgie'", Reuters reported.
A "wedgie", usually done as a prank, involves pulling the victim's underwear to the upper torso.
"Davis allegedly pulled the elastic waistband of Mr St Clair's underwear over his head and around his neck," said the affidavit.
Ms Amy Elliot from Oklahoma Medical Examiner said the cause of death was asphyxiation and blunt force trauma.
Pottawatomie County Sheriff Deputy Travis Palmer said both men were drinking beer on the night of Dec 21 at the older man's residence when Mr St Clair began speaking ill about his wife, who is Davis' mother.
Mr St Clair's elastic waistband was stretched over his head and it left ligature marks around his neck.
Blood splatter was also found in the kitchen, living room and on the living room ceiling.
At a hearing on Wednesday, Davis told the judge: "Things got out of hand."
He said he got into a fight with Mr St Clair and knocked him unconscious. He then pulled Mr St Clair's blue underwear and stretched it over his head from behind.
He said he wanted his stepfather to be embarrassed when he came to.
Davis' sentencing is set for July 16.
Prosecutors are seeking a 35-year prison term.
