Feds Use Urban Dictionary to Press 'Murk' Charges Facebook poster accused of making threat online By John Johnson, Newser Staff Posted Sep 3, 2011 11:13 AM CDT 12 comments Comments A screen shot of the offending definition. (Urban Dictionary) (Newser) – An Indiana man who threatened to "murk' the manager of a gun shop is in hot water thanks to UrbanDictionary.com. After the 27-year-old posted the threat on Facebook, ATF agents consulted the online slang guide and found that it means to beat someone to death, reports the Smoking Gun. They charged Justin Kemble with sending a death threat online, a case backed up by paper printouts from the dictionary site. He's been jailed in advance of a hearing next week.
