pantiler

From pantile + -er. Hotten suggests a derivation from the slang pantile (“hat”), because of the distinctive sugar-loaf hats worn by Puritans, or the habit of Quakers and many Dissenters of not removing their hats in a place of worship; or else from pantile (“type of roof tile”) with which the meeting-houses of Dissenters were usually covered.
