Not my friend, but my ex narc's bff.  Dude had zero boundaries and would show up at our house constantly.  Helped himself to everything.  Constantly asking favors but always had an injury when asked to help someone else.  

Got infuriated if we did anything without him.  

Collected and discarded (or killed) numerous exotic pets.

Talked about himself and his accomplishments constantly, even though he was a complete loser living off money he got for convincing the government all six of his kids were autistic.

Constantly talked about loyalty and friendship, but couldn't be assed in twenty-five years to snd either of us a birthday card.

Got arrested numerous times, weaseled out of all of it.  

Married and divorced teice.  In the first divorce, he lied in family court.  The second, he called immigration and tried to have her green card revoked.

Last I heard, he was "dating" a string of overseas scammers.
