I overheard this word on the telly. I didn’t know what the programme was about, but I liked the sound of the word, so I looked it up.

Pullulate means to breed or spread so much that one becomes extremely common! This sounds appalling, but I don’t think it means that you go down the social scale every time you have an extra child – more that any population that is on the increase, as in the grey area on the mean distribution graph shown, is pullulating. Once the population is in decline I guess there is another word?

It comes from the latin word that means sprout. I’m sure there is a joke in there somewhere.
