"neatnik"

1. Slang. a person who is extremely neat about surroundings, appearance, etc...

"This yard scrubbing leaves the neatnik poised and ready to intercept the very first leaf to yield to gravity."

Origin of neatnik: Neatnik was formed in opposition to the supposedly scruffy, unshaven beatnik (coined in 1958). The suffix -nik, still unnaturalized in English, is of immediate Yiddish origin, from Slavic (Russian, Ukrainian). English peacenik, also derogatory, dates from 1962. Neatnik entered English in 1959.
