The practice of stealthily avoiding buying your round of beer at the pub.

Waiting until others are so drunk that they don't notice you never bought a round of pints during the evening.
Eoin: "Who's round is it?"
Pete: "I bought two rounds of 7 pints already tonight".
Eoin: "Me too, Steve how many rounds did you buy?"
Steve: "Oh ho, I bought the last round"
Paul: "No you didn't, you ordered it but I payed for it!"
Eoin: "Steve, you've been merning again!"
