witnessing a playboy and a pathological liar

I'm a fresh grad and in my class, there was one guy who was well known to be a playboy in the masses and a pathological liar to those close to him. This was my first time witnessing such a person so I would like to enumerate some of his many traits to spread awareness.

1. He used to play the victim card to gain girls' sympathy and eventually make them fall for him all the while having no actual intention of being sincere to them. Im not one of his dalliances but he used to be my friend at the very beginning of our degree and he has tried this victim card on me too. He was very convincing and he actually made you sympathise with the false persona he put on.

2. He would tell others that such and such is trying to get close to me and I dont want that at all AT THE SAME TIME courting that person.

3. He would backbite about other people to the girls he was with and would backbite about the girls to those same people.

4. He would be in multiple situationships and relationships at the same time. He would pit the girls hes with against one another. Once, 2 girls caught him in the act of fooling with them at the same time and publically humiliated him, deserved.

5. He would make things up- absolutely unnecessary things about himself that my father is so and so and my family is falana- all of it bullshit. He would lie about things; and had an air of false grandiosity to himself.

6. He would manipulate his friends and Im sure he has no real friends at this point because of his antics.

It was my first time witnessing such a twisted creature and I have to say it was quite an experience. Its also quite scary to know that so many people like him are out there and you never know before falling victim to such a person. Beware, and TRUST THE PEOPLE AROUND YOU WHEN THEY ASK YOU TO STAY AWAY FROM SOMEONE!
