Angoulême : noun The mouth - in the slang of the thieves, who borrowed this word from the slang of the people, by corruption of the old verb engulf, swallow, and not, by a more or less ingenious and more or less well-founded allusion to the reputation of gluttony of the capital of Angoumois.
In the XNUMXth century, people said jokingly "Go to Angoulême" to "swallow". it was a pun taken from the verb engouler (to swallow), where we find the Latin root greediness (throat) which gave mouth and its derivatives.
