Mock

English (Devon): from the rare Old English masculine personal name Mocca, which may be related to a Germanic stem mokk- ‘to accumulate’, ‘to be heaped up’, and hence may originally have been a nickname for a heavy, thickset person. Alternatively, it could be from Middle English mokke ‘trick’, ‘joke’, ‘jest’, ‘act of jeering’, a derivative of mokke(n) ‘to mock’, from Old French moquer.
