Splashing is an informal game term. To "splash" a card is to run a card from outside the main culture(s) or strategy of your deck. Úlairë Enquëa, Lieutenant of Morgul (1U231) is one of the most famous splash minions. You can run it in almost any deck, as it doesn't require any other Wraith culture cards to work. Gollum and Gandalf cultures are often called "splash" cultures, as many decks run companions or minions from those cultures to supplement a different culture's weaknesses.
