Overset
A player has a set if he makes a three of a kind with two of his cards and one of the board‘s. A player has an overset if he has a set that is higher than another player’s set.
Example (Texas Hold’em):
| Player A | Player B | Flop |

Player A has a set of nines, B has a set of kings, and therefore an overset.
