A pasquinade is a satire, usually done in writing and posted in public. A skit, flyer, or cartoon can be a pasquinade — as long as its intent is to mock or ridicule something or someone.
You can find examples of modern pasquinades on late night television political sketches and in newspaper political cartoons that mercilessly make fun of public figures. Today, you’re probably more likely to use a synonym for pasquinade, such as lampoon or satire. But neither of those words can say they got their name from Pasquino, a 500 year-old statue in Rome where people posted lampoons and satirical poems.
