From today's World Wide Words, ed. M. Quinion:

CRITICASTER From Andrew Haynes: "Your Weird Words piece mentions
some other words that use the '-aster' ending but it omits one that
may be useful in that it no doubt describes some of the people you
encounter through World Wide Words. That is 'grammaticaster', a
contemptuous term for a petty or inferior grammarian, which now
appears only in dictionaries of weird words but does have the
cachet of having been used by Ben Jonson, who wrote in a work
entitled Poetaster: 'He tells thee true, my noble Neophyte; my
little Grammaticaster, he does.'"
