self-defecating humor 

The act of getting some cheap laughs by pooping one's pants.

Billy's lame jokes kept falling flat, so, desperate for a laugh, he decided to change course and try some self-defecating humor.

SELF-DEFECATING HUMOR 

Not to be confused with self-deprecating humor, self-defecating humor is NOT funny. A joke that bombs like a dump of crap.

Example: A joke about your own foibles that stinks!

Sorry,Man, I hate to admit it, but I like PB&J with bacon even though it always gives me gas. (Your admitting that is self-defecating humor.)

Too much information, Dude!

self-deprecating humor 

Humor where you put yourself down.
Sometimes funny, but sometimes overused fishing for compliments or a signal of low self-esteem.

ex. 1

ex. 2

Self-deprecating humor 

A type of extremely stale humor, mostly used by youtubers to deviate criticism, desperately make a joke, make up for bad quality of videos and/or appear naive to an audience.

Youtuber: hey guys sorry for the low quality of videos for the past years and the constant manipulation of my subscribers, but hey i’m dumb and i have a small penis, so what did you expect LMAO

Audience: oh that doesn’t matter, we completely forgive you, you used self-deprecating humor and clearly see your faults!

When you laugh so hard you shit yourself.

John's self-deficating humor was so potent he cleared the room.
