Pet form of Patricia or Patrick. It is generally a girl's name; as a boy's name it is almost completely restricted to Irish communities. Its popularity does not seem to have been seriously affected by its use in derogatory senses in the general vocabulary, in America meaning ‘a dupe’ and in Australia ‘a homosexual’. It is sometimes used as an independent girl's name.
Respelling of German Backofer, a topographic name for a person living next to the village baking oven or a metonymic occupational name for a baker, from back(en) ‘to bake’ + ofen + the suffix -er denoting an occupation. Alternatively, though less likely, it could be from Bockhof(f)er, a habitational name for someone from Bockhop near Vechta.
