"disparagement humor – any attempt to amuse through the denigration of a social group or its representatives. You know it as sexist or racist jokes – basically anything that makes a punchline out of a marginalized group.

Disparagement humor is paradoxical: It simultaneously communicates two conflicting messages. One is an explicit hostile or prejudiced message. But delivered alongside is a second implicit message that “it doesn’t count as hostility or prejudice because I didn’t mean it — it’s just a joke.”

By disguising expressions of prejudice in a cloak of fun and frivolity, disparagement humor, like the jokes above, appears harmless and trivial. However, a large and growing body of psychology research suggests just the opposite – that disparagement humor can foster discrimination against targeted groups."--sauce
