Mentional Liar 

You mention something that you are serious about, but don't ever follow through with it.

Dad: Lets go to on vacation (completely serious tone)
Daughter: OK WHERE!?
Dad: Las Vegas
Daughter: when?
Dad: maybe next year
...3 years later...
Daughter: You are a Mentional Liar!! For the last 3 years you said that we could go to Vegas!

Purvin Liar 

Someone who is completely full of shit. Says one thing and does another. He criticizes people playing for him while he does the same shit behind your back. Someone who temporarily coaches the Jacksonville Jaguars until more leaks surface. Someone who used to coach in college where he could just recruit better players than other schools. Someone who is a complete fraud and a liar. Someone who likes to leave the wifey at home while he tries to perv out with women half his age. Someone who likes lap dances while avoiding his wife's calls. Someone who cant be trusted. Probably hangs out with Jon Gruden and Former Governor Cuomo and had Jeffrey Epstein on speed dial.

I went to hooters the other day and almost choked on my wings while looking over and seeing Purvin Liar trying to get a lap dance from the waitresses.

pathalogical liar 

A person who just can't help but tell the exact opposite of what is the truth. You will know that nothing but prefabricated bullshit is coming out of their mouths WHEN THEIR LIPS ARE MOVING! They lie about everything from if they cheated on you to what color the icing was that topped their poptart for breakfast. And they can be perceived as being passionate when telling lies, because along with a fake life of lies comes the job of being an actor. A Pathalogical Liar will even continue to repeatedly tell lies, EVEN after the fact that they DONT DO IT WELL, is pointed out to them time and time again.

DANNY is a pathalogical liar! And , ACCORDING TO HIM, he also has did not screw Leanne or Dana...did not call my parents and tell them a bunch of LIES and some truths about my personal life, he did not steal from me, he will find a way to help me pay the bills, he is sorry for calling me names and being mental and abusive, he is sorry for being a complete leech and mooch...doing NOTHING..not looking for a job, smoking all of my cigarettes, suffocating me, living off me and draining me mentally , physically, emotionally...for doing nothing but being a complete burden and being more work than five newborn babies...but these are all lies because has not stopped. I think being a pathalogical liar makes DANNY really disgusting...He definitly needs more D to go with that ICK!

Artistic Liar 

A person with a bachelor's degree in political science has an honorary master's degree in the liberal art of the lie.

I never would have believed he would succeed in politics with a liberal arts degree, but I guess he was an artistic Liar.
