A linguist, so he claimed, said the only use he could find was in a play by Shakespear. It was "Mommick a string". Gee, worry a string, a knot, beads, etc.
Haven't you mommicked the life out of me this day!
A Mother to a child. The only way I've ever heard it used. Yeah I'm from coastal NC. Morehead City. My Aunts from Wades shore on Shackleford (1880's)used it this way as did the younger of my sisters. Newer uses have apparently arrived. Evolution.
