From the Play "Loves Labours Lost"
Shakespeareâ€™s wondrous creation appears in Act 5, Scene 1:
I marvel thy master hath not eaten thee for a word;
for thou art not so long by the head as
honorificabilitudinitatibus: thou art easier
swallowed than a flap-dragon.
It was the name given to a game in which the players snatched raisins out of a dish of burning brandy and extinguished them in their mouths before eating them. By extension, it was the burning raisins used in the game.
