E.C.S.B.T.D

A "Eustace Clarence Scrubb Before The Dragon"
This references a bothersome and unfriendly character in The Chronicles of Narnia, who shows up in The Voyage of the Dawn Treader," "The Silver Chair," and "The Last Battle."

Eustace was quite a bore and very tedious to everyone before he was turned into a dragon and learnt his lesson.

"My brother is being a real E.C.S.B.T.D today, he keeps lecturing me on the British Consul!"
