"Badger- a native animal of Wisconsin"
A badger is a short stout mammal with powerful front claws for digging and has a striking black and white face. To badger someone would mean that you are constantly doing something to a person that probably annoys him or her. Wisconsin is known as the "Badger State", and a native of Wisconsin may, in fun, be called a badger.
The word "badger" is first recorded in 1523. Linguists think that it may be linked to the white and black markings on a badger's head. The striking markings and the badger's courage in defending itself could have led people to think in terms of a knightly "badge." "Brock" is a British word that refers to badgers and it is thought to have a Celtic origin.
