A term used to describe someone who is for the most part begging. However, this is used loosely. for example someone who is complaining a lot is begging. If you are playing Tiger Woods PGA Tour '07 and you are putting with reckless abandon, "that's beggar." If you are hating a player or the game in any sport or game, "that's beggar." Basically, any act or state of mediocrity exhibited by a person, place or thing. Additionally, the term can be used to reference a person exhibiting bitch-like behavior.
