Stands for "Mushroom Cloud Layin' Motherfucker, Motherfucker!" Jules says this in the movie Pulp Fiction and it is generally used to describe one who is a bad ass. Often referring to high speed types in special ops units.
"Well I'm a mushroom-cloud-layin' motherfucker, motherfucker! Every time my fingers touch brain I'm SUPERFLY T.N.T, I'm the GUNS OF THE NAVARONE." Hence, MCLMM.
