quasimodo (n.)

"Low Sunday," 1706, Quasimodo Sunday, from Latin quasi modo, first words of introit for the first Sunday after Easter: quasi modo geniti infantes "as newborn babes" (1 Peter ii.2). The hunchback in Victor Hugo's novel was supposed to have been abandoned as an infant at Notre Dame on this day, hence his name. For first element, see quasi; for second see mode (n.1).
