Generic term used as a noun, verb, adjective, exclamation and adverb by incredibly vocab-limited Hood-persons as a lazy form of the too-many-syllabled "mutherfucker", which of course refers to the fact that since the actual lineage of many hood-persons is unclear, that having sex with a female hood-person may in fact be having sex with one's own mother (unless she's younger than you are.)
