horseshoe fandango 

After the Great Ban of June 2006 on the Weebls-Stuff Forums, this was a word that, whenever used in the Cheese Bin, everyone not banned would pretend it was a funny joke made during the sentence of the banned forumites in order to make them feel left out.

Mr Salek: Hey guys, remember Horseshoe Fandango?
Other forumite: Lol! That was so funny!
