lubber

noun

Etymology: From Middle English, perhaps from Old French lobeor (“swindler”), or of Scandinavian origin, compare dialectal Swedish lubber. The grasshopper was likely so called after sense 1 (“a clumsy or lazy person”).

1. A clumsy or lazy person.

   “[T]hree of the boys, of whom Mr. Hector was sometimes one, used to come in the morning as his humble attendants, and carry him [Johnson] to school. […] The purfly, sand-blind lubber and blubber, with his open mouth, and face of bruised honeycomb; yet already dominant, imperial, irresistible!”

2. An inexperienced or novice sailor; a landlubber.
3. An eastern lubber grasshopper (Romalea microptera).
4. Alteration of rubber.
