Tear-mouth

You grow rich, do you, and purchase, you twopenny tear-mouth?

How would you, or how do you think I should, relish being the object of such a letter as Kean wrote t'other day to a poor author, who, though a pedantic blockhead, had at least the right to be treated as a gentleman by a copper-laced two-penny tearmouth, rendered mad by conceit and success?
