To attack and destroy without warning, the ship of a pilot in the same player-created corporation. Named after the first widely known EVE pilot who did so. Note: CONCORD does not respond to same-corporation attacks, but DOES respond to same-alliance attacks. In nullsec terms, this term refers indiscriminately to any hostile action taken against a target considered to be friendly (generally speaking, any positive standing is considered friendly).

Also means to steal from the alliance/corp funds or hangars (including from a player owned starbase).
