Someone with large teeth who likes to steal boyfriends/girlfriends they are a grass beaver because they have a tendency to talk to you as if they are your friend but eventually end up helping your boyfriend/girlfriend cheat on you with them or other people. These people also have a tendency to denie it when you confront them about it. Watch out for grass beavers at all costs.
