Lazy Mutha Fucka or Lazy Muthafucka or LMF is a Cantonese hip-hop group in Hong Kong. The group, signed by Warner Music, was founded in 1993 and disbanded in 2003. The members from the disbanded LMF are now pursuing their solo careers.

Their songs are very controversial because of their influence on Hong Kong youth and hip-hop culture and attitude, even making references to Triad societies such as the 14K Triad.

LMF offers Hong Kong an alternative to the overpopularized sentimental sop of Cantopop. LMF remains one of the few, if not the only, well-known localized rap groups. While American hip-hop focuses on racism and political oppression, LMF highlights the economic oppression and social alienation faced by the lower class of Hong Kong, all coming from Hong Kong's overcrowded public housing estates. In essence, LMF uses Bruce Lee as a role model of a generation of Chinese youth.

Their last and final album, finalazy muthafucka, was released just before their breakup. Read more on Last.fm. User-contributed text is available under the Creative Commons By-SA License; additional terms may apply.
