An anti-proverb or a perverb is the transformation of a standard proverb for humorous effect. Paremiologist Wolfgang Mieder defines them as "parodied, twisted, or fractured proverbs that reveal humorous or satirical speech play with traditional proverbial wisdom". They have also been defined as "an allusive distortion, parody, misapplication, or unexpected contextualization of a recognized proverb, usually for comic or satiric." To have full effect, an anti-proverb must be based on a known proverb. For example, "If at first you don't succeed, quit" is only funny if the hearer knows the standard proverb "If at first you don't succeed, try, try again." Anti-proverbs are used commonly in advertising, such as "Put your burger where your mouth is" from Red Robin. Anti-proverbs are also common on T-shirts, such as "Taste makes waist" and "If at first you don't succeed, skydiving is not for you".
Standard proverbs are essentially defined phrases, well-known to many people, as e. g. Don't bite the hand that feeds you. When this sequence slightly changed (Don’t bite the hand that looks dirty) it becomes an anti-proverb.
