Leng

Leng (noun / adjective / verb / UK slang)

(Also heard as Lengman or Leng off)

Definition: Most commonly a firearm or gun on road. It also gets used as an adjective for an extremely good-looking girl (“she’s leng”), or a verb meaning to shoot or knock someone out cold.

Pronunciation: /lɛŋ/ (rhymes with peng and bang)

Where It Comes From: It kicked off in London’s Jamaican-influenced street culture and Multicultural London English (MLE) around the late 90s and early 2000s. The word is basically onomatopoeia—mimicking the loud, ringing crack of a gunshot (“leng!”). Early grime pirate radio sets and UK road rap tracks cemented it as street code for a piece. As London slang naturally crossed over with words like peng, younger crowds also started flipping it to describe striking looks or violent hits in general.

How People Actually Use “Leng”: Context tells you everything here.

In UK drill and rap lyrics, if an artist mentions “holding a leng” or tells someone to “back out the leng,” they are strictly talking about pulling out a weapon. But down the pub or on TikTok, teens and young adults might drop it as a straight swap for peng—spotting a gorgeous girl across the room and whispering to a mate that she looks “proper leng.”

Examples in the Wild:

• “He was acting all brave until the other lot backed out a leng.”

  Translation: “He acted tough until the rival group produced a gun.”

• “Look at her profile picture mate, honestly she is pure leng.”

  Translation: “Take a look at her photo; she looks exceptionally attractive.”

• “One clean right hook was enough to leng him straight onto the pavement.”

  Translation: “A single solid punch knocked him out flat on the ground.”
