A set of rakes in the eighteenth century, who, with the Nickers and Mohocks, committed great annoyances in London and other large towns.
“Who has not heard the Scowerers' midnight fame? Who has not trembled at the Mohocks' name? Who there a watchman took his hourly rounds, Safe from their blows and new-invented wounds?” Gay: Trivia, iii.
