Off-color humor is humor that deals with topics that may be considered to be in poor taste or vulgar. Many comedic genres may incorporate "off-color" elements.

Ribaldry or blue comedy is humorous entertainment that ranges from bordering on indelicacy to indecency. Blue comedy is also referred to as "bawdiness" or being "bawdy". Like any humour, ribaldry may be read as conventional or subversive. Ribaldry typically depends on a shared background of sexual conventions and values, and its comedy generally depends on seeing those conventions broken.
