> DOJ gets Sammy "The Bull" Gravano to testify as to the meaning of '86' in Comey trial

He wants a pardon.

The number 86 is best known as a popular American slang term meaning to cancel, throw out, or get rid of. Slang and Cultural Meanings: Restaurant and Bar Lingo: Widely used by kitchen and wait staff to mean a menu item is sold out, or to eject a disruptive customer from an establishment.

Origin Theories: Popular theories suggest it started as 1930s soda-counter rhyming slang for "nix," or from the historic Prohibition-era bar Chumley's at 86 Bedford Street in New York City where patrons were told to exit during police raids.

Other Contexts: Opinions on older folklore—like mobsters driving 8 miles out and 6 feet under—are considered myths by language experts, though the term has filtered broadly into fiction and general pop culture to mean getting rid of something.
