self deprecating 

Insulting; devaluing; or belittling oneself, often in a sarcastic or humorous way.

Young girls are so self deprecating. They never talk about anything but their flaws.

Tate: I have to cancel our plans this weekend!
Lana: Don't worry about it; I'm an expert when it comes to spending weekends alone.
Tate: You're so self deprecating sometimes, Lana.

Self-Deficating 

The act of shitting ones own pants, most often resulting from an embarrassing situation.

The drama-queen was so drunk last night that she didn't know what she had said and done. When we told her, she ran into a corner and started self-deficating. Sadly, her act of self-deficating only made her more embarrassed, and she self-deficated again. It was a vicious and smelly circle she got herself into.

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

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!
