JAMF was NOT invented on Sanford and Son, nor by Clint Eastwood (etc.) although Redd Foxx was certainly hip to the original usage/meaning and used it to "slide one by" the uptight whiteboys on the Standards and Practices committee of his network. JAMF is an acronym for Jive Ass Mother Fucker, a black slang term coined in the late 1930s or early 1940s by jazz musicians, for use in "polite society" when ragging on someone. The word may have other uses/meanings at this late date (it's the title of an Apple multiple device management platform, for instance) but this definition is the correct one. Sometimes spelled "jamph," as in the Maynard Fergusson song title.
