Perk

1. (thing) Short for perquisite, a perk is a fringe benefit that comes with holding a particular position or that is awarded instead of a raise. In the US, for example, members of Congress have the privilege of franking (sending mail with their signature in place of postage). Perks might include a company car, a better parking space, or an employee discount on the company's products.
    
2. (idea) Short for percolate. One perks coffee by preparing it in a percolator-style coffeepot.
