True. Johnny Thunders Rocks and L.A.M.F. is one of his great records. However, L.A.M.F. is not punk graffiti but gang graffiti. In New York City (johnny's home) the gang members would stray into other gangs territories where they would tag D.T.K. meaning "Down to Kill", a challenge to the gang who's turf it was.

How-ever 'talented' and/or 'artistic' its members were, they were well known for their hardcore activities and indulgences, sometimes resulting in members' deaths, hence their behavior living up to their name 'suicidal'. Interests of the group included death metal music, a singular addition to the normal hip-hop association of graf crews (resulting in the sometimes used Mass/or Melbourne Satanic Alliance/Allegiance tag), and excessive drug and alcohol consumption. M.S.A. were actively pursued by various police groups for their prolific graffiti of urban infra-structure including Australian trains and also were accused of engaging in occult-like practices and satanic activities, possibly actually involving the associated group, S....

Like a Mother Fucker. Also spelt L.A.M.F. and always capitalized.

Although two current UD definitons have it as 'punk' origin and used in the 70s, it was widely used as early as the 50s in Brooklyn and other areas of NYC and possibly beyond.

It was also frequently preceeded (separated by a space) by D.T.K. = Down To Kill
and followed less often by TTH = To The Heart
