mama bear(redirected from mama bears)
1. A strong, aggressively protective mother. Likened to literal mother bears, which are notoriously violent and aggressive when confronting a danger to their offspring. She's usually quite demure and reserved, but she turns into a straight-up mama bear if you so much as look at her kids the wrong way.
2. A female police officer. The two fellas were busting each other up when a mama bear on patrol came round and threw them both in her squad car.
n. a policewoman. (see also lady bear.) As we came under the bridge, we saw a mama bear sitting in a pigmobile.
