v.1. To damage or batter someone or something: Whoever tried to park that truck bumped up my car pretty badly. The skiing accident bumped me up a bit, but I'm okay.
2. To move someone to a higher position in a list: The doctors bumped up anyone who needed immediate medical attention to the top of the list. My friend at the theater bumped me up in the line for tickets.
3. To raise something or someone to a higher category or level: The store had to bump up their prices when the price of heating oil went up. All I had to do was ask, and the airline bumped me up from coach to business class.
