>>My guess - rhymes with "pumpkin"
LOL, true- apart from those who say "punkin," pumpkin would sound similar if spelled pumkin.
I did not do Dragan the disservice of responding with the predictable schoolboy crudity when he asked where the p came from. ;-)
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
