Three alternative Bs for you today:
bloviator: one who goes on and on about subjects they really don't understand.
bayard: one who has all the self-confidence of ignorance.
blatherskite: a garrulous talker of nonsense.
(On a lighter note, a boffola is an uproariously funny joke.)
I have been asked by a lot of people how I made my fortune
Well , I bought car aerials for £1, sold them for £1.20 . Went on and bought more sold them and bought even more and sold them and so on.........Then my uncle died and left me £500m
Crapulent and crambazzled: two words born from excess. They mean, respectively, decidedly hungover, and prematurely aged from too much drink/food/partying etc.
