Hole Card
The 'house' usually refers to any and all aspects of the actual pokerroom. The 'house' sets the rake, and rules (house rules) where they might be different than normal.

'House' is also a term used for a poker hand, a Full House. A full house is a very strong poker hand, in which a player has three cards of one rank and two cards of another rank. A hand containing three aces and two kings would be called 'a house of aces', 'aces over kings', or 'aces full'.
