A man who cannot be responsible enough to keep his privates in his pants, and habitually thinks of only eating, sex, drinking, partying, sex, sports, sex, sleeping, sex, women, sex, and truly believes everything and everyone else is beneath him, and his needs/wants.

A man doesn't necessarily have to be sleeping around with others, but can be sexually demanding, and even sexually abusive to his significant other. Sex dominates every day of his relationships. Irresponsible, and inappropriate behaviors are common. Self induced thoughts of indiscretions from his significant other, and acting upon those self induced thoughts, against a partners will.

A man that gives into all his issues whether they are dangerous to him, or others, and either see's no issues with the behavior, or does see the issues, but refuses to acknowledge his weakness's and seek help.

A man who will have sex with anything that moves.
Someone who is self centered enough to ignore everything and anything except for their own needs, and wants. Who either refuses, or actually can not see how their thinking and actions is destroying the other people in their lives.

Someone who will have sex with anything, or/ and anyone without thought of consequence. And because this man thinks, breathes, and see things in that way, they are considered a Neanderthal Dog. A unfeeling, unthinking, non-understanding, non-caring individual, who will "rut" with anything that moves...thus a dog. Neanderthal Dog.

A (COPYRIGHTED) term which originally referenced one unfortunate teenage girl who strongly resembles a Cro-Magnon female in appearance. Now used as a nickname to describe any female who resembles a Neanderthal, but to distinguish from the original Neanderthal Girl, the town is added to the name. Example: PCNG (Port Charlotte Neanderthal Girl).
None of them can beat the original though.
The mythological residence of the so-called "Modern-Day Neanderthals" is a place called "Neanderpines" supposedly located near Tampa, Florida. However, in real life, these Cro-Magnon lookalikes can be found in any community across America, though the original, and many others, are found in south Florida.
Some common characteristics of Neanderthal Girls include, but are not limited to, the following: Extremely bushy eyebrows (or a unibrow); protruding brow bones; crooked, yellow, or just plain BAD teeth; an overly large and misshapen nose; really ratty, greasy, frizzy, unkempt hair; a protruding and/or overly square jaw; short stature; and possible (though not proven) uncanny ability to hunt and make stone tools, with little knowledge of agriculture as it prefers a more primitive method of hunting and gathering.
Personality wise, they are annoying, intelligent but hopelessly lacking in the common sense department, irritatingly random, and think they are attractive.
The theme song of Neanderthals everywhere:
"I'm a Neanderthal man, you're a Neanderthal girl, let's make Neanderthal love, in this Neanderthal world."

"Where can you see Neanderthals? Only in Neanderpines."

An ideology that views Neanderthals as supreme to homo sapiens. A view so niche that it could only be held by fat, sperging self-proclaimed 'cavemen' who've failed in every aspect of life to the point of coping by calling themselves Neanderthal supremacist.
Hey, David, see that fat, smelly idiot over there? What's the deal with him
Oh, Mike, he's just a Neanderthal Supremacist

The kind of people (both male and female), who instinctively only care about breeding with a cute/attractive counterpart. They are usually not very well educated and spend their time in bars scouting for potential victims of their blissful ignorance on using others.
