self-deficate 

Using Insults and Demeaning Terms to define yourself, in an attempt to either make others feel sorry for you, or make yourself a target of their anger.

Basically>Verbally Shitting On Ones Self.

Self-Defication is usually over the top and vastly overkill. Sometimes people with Schizophrenia and bi-polar disorders are prone to this. Note Also Drug addicts are to prone to it.

#1 " You Fucking suck #2, fucking dick"

#2 " Yeah That's Right, I'm A DICK! I Suck yup, suck suck suck huge dick!... I'll go to Mexico and go blow one now! Cya." *door slams behind #2*

#3" What Was That?"
#1" That There is a self-deficate, in active form you'd call it self-defication, basically #2 is going for pity and a nice self-hate session, as most of Emo kind cannot stand being happy"

(Note: the overblown retort and return self-insulting are greater than the initial insult. this signifies a Self-Defication)

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.

When you laugh so hard you shit yourself.

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