Pushulate

Pushulate: verb. Die out or go into hiding, so as to become extremely rare or scarce. This word was created by Noah Webster as an antonym for pullulate, when he was composing the second version of his dictionary and was horrified to discover, that some moron had come up with pullulate, but hadn't made the obvious logical step to pushulate. Webster was so dumbfounded he requested an executive order from President Monroe to immediately make the word a mandatory part of elementary school curriculum. Although the order was immediately overturned by president Adams, it was still the most consequential part of Monroe's presidency.
