The term Jantomafia just tends to get thrown about by the anybody but Ianto crowd as a derogatory term for anyone who happens to like the Jack/Ianto pairing. Because you know ship wars are so terribly amusing and clever. Yawn!

Although if everyone who likes Jack/Ianto is part of the mafia I think we need to start working on our code names, organisational structure and natty suits.

I'm kind of with you on the prompt table concept - as soon as I see one I run a mile.
