Responding To Netizen's Comment

Netizen: What are pathological liars? And how do I know one when I see one?

Response: Pathological liars is aka pseudo-logia fantastica or mythomania. Pathological liars often lie when there is no need to, his lies unwarranted and uncalled for ... and bereft of any plausible reason. Their lies are gratuitous ...lacking in apparent cause or justification.  They succumb to lies and the invitation to fib is overwhelming and irresistible. 

Making up stories becomes compulsive and made-up scenarios are large-scale and wide-ranging. The urge is relentless and uncontrollable it becomes a mortal sin if they can't lie in a day. Even if his habit of lying has already caused him a lot of misery and problems, there is no stopping this man ... even when he is on the precipice of getting caught.

Just to remind everybody, pathological liars are not included in the list of mental health diagnoses and DSM-5. But using the term pathological means there is underlying pathology or illness imbued why the person continues to lie. If a person lies 5 or ten times more in a day, he is included in this category
