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.
