Brown noser

[Becky]

A person who acts favorably to his or her peers to gain stasis or fancy that will eventually be used to their advantage. Such as a raise, promotion, or acceptance in a group. Usually brown nosers will do anything to gain the approval of their person of choice. These people can also be described as losers because they can’t work for what they want, instead they play dirty and butter-up the boss/teacher/peer into getting what they want. Another word for this person is a shoe shiner or a rough translation of brown noser in Spanish is, an eye licker.
