look up any word, like ethered:
On democraticunderground.com, during the summer of 2009, Seven Gay posters were banned within a 24 hour period for the crime of disagreeing with Obama administration policies. One member (after the original 7 were banned) got banned for just posting the number 7. This time has been called the Great Gay Purge of 2009. As a result, at least 23 long time members were banned from the site.

Posting a Seven is posting something deliberately to be banned from a message board.
"I don't blame you for not posting a seven, since you have a huge target on your back.
