Just like the term Rubber duck debugging, which is in software engineering, a method of debugging code. The name is a reference to a story in the book The Pragmatic Programmer in which a programmer would carry around a rubber duck and debug their code by forcing themselves to explain it, line-by-line, to the duck. Many other terms exist for this technique, often involving different inanimate objects.

The "coffee mug debugging" is the same method of debugging code with which developers force themselves to read and explain their code line-by-line, to the coffee mug. There are developers who calls this planted plot debugging as well. But "coffee mug debugging" seems more convenient at this century since it's easy to find a coffee mug for a developer than a "rubber duck" or "planted plot".
I had done coffee mug debugging for my dart code in flutter and found out a syntax error and fixed it.

Durring intercourse, when the man cums inside a womans vagina and the woman shits herself while he is cumming.
"Dude how was it??? She looks fine" ... "man this chick is crazy! I asked her how she wanted it and she said fuck me as hard as you can.. and when I was finishing, she looked me in the eyes and pooped all over my bed sheets! I pulled out and was like what the fuck!! And all she said to me was... 'whoops I spilled my pink coffee mug' "
