clamjamphry n.

also clamjamfery, etc., contemptuous word for "a collection of persons, mob," 1816 (as clanjamfrie), of unknown origin; first in Scott, so perhaps there's a suggestion of clan in it, or perhaps clam, clem "mean, low, worthless." Second element seems to be related to Scottish jamph, jampher "to mock, scoff; be idle."
