What do you mean by dirty, yellow, gray and black jokes? I really appreciate it．

Yellow jokes are jokes or stories that contain indecent content such as yellow.

The yellow paragraph is the same as above

Gray jokes refer to people who laugh before thinking. Generally speaking, they write jokes mainly on the dark side of things, and criticize the current shortcomings with helpless ridicule and criticism.

Black jokes refer to short and pithy horror stories, which are bizarre, scary and supernatural, but gripping.
