[also spoiler spoo or spoiler protection] A screenful of blank or spacer lines deliberately inserted in a message following a {spoiler} warning, so the actual spoiler can't be seen without hitting a key. Formfeeds used to be used for this, but are now rare because so many people read news through Web interfaces on which they have no good interpretation.
