A
ridiculous, silly or stupid person.
The word 'dingbat' originally refers to to a character or symbol used in typesetting which gives an
instruction to the printer. These should be removed before the text is published, but were occasionally left in by mistake. The character made no sense to non-typesetters and the
association of "dingbat" with "nonsense" and "forgetfulness" carried over to describe people.
Julia's such a dingbat, I asked her to buy me yogurt and she got me cream.
This end of year report is riddled with inaccuracies. Looks like we've got a dingbat
in the mix.

Nice one Paul, a
spectacular display of ding-battery.
