Definition of «lied on 50»

"Lied on 50" is a specific slang expression originating from regional street culture, particularly within the Chicago drill music scene, where "50" refers to a specific block, set, or neighborhood affiliation (often 50th Street). To "lie on" a set means to make false claims about one's actions, loyalty, or street credibility involving that specific group. The phrase is used to call out perceived phoniness or to mock someone who has been caught in a lie regarding their gang ties or criminal exploits. It carries a confrontational and serious tone, as misrepresenting one's affiliation is considered a major sign of disrespect in these communities.
