(noun)
In short, someone who will bend over backwards to blow the guy looking over their shoulder.

An individual who makes frequent, obvious, and sometimes disingenuous attempts to impress, please, or win favor with people who are either in a position of authority over them, or who have something that they want. One can be a suck-up because they wish to gain something tangible (promotion/pay, favors, gifts, etc.) by pleasing the other person, or because of a pathological need to be liked by others, the former being more common. At least a few suck-ups can be found in most workplaces.
