posimistic 

A posimistic person is someone who has a very positive, affirmative, optimistic, favorable outlook on life.

It's actually a combination of the words postive and optimistic, hence " posimistic", "posimist " & " posimism ".

The opposite would of-course be "negamistic" , "negamist ", " negamism ", which is a combination of the words " negative " and " pessimistic " !

"Charlie is always posimistic, expecting the best in this best of all possible worlds, but sooner rather than later he must come to the realization that he cannot have his cake and eat it too !"

Cautiously Pessimistic 

An increasingly relevant wordplay on the cliché "cautiously optimistic". As the world continues in free fall, its much more realistic to expect negative outcomes. Therefore, its much more pragmatic to maintain a cautiously pessimistic demeanor, rather than a cautiously optimistic one.

My cat is always cautiously pessimistic when inspecting anything new that I bring into the house.

Easily the most negative person in a group of people that are otherwise having a great time. But instead of keeping it to himself, it becomes his mission the fuck the fun up for anybody that looks too happy.

BRO 1: Hey I got these four girls to come back to chill with us at the house!

BRO 2: these girls don't like you bro, they're just gonna smoke your shit up, drink the liquor and leave. I bet at least two of them have the herp, either way this shit is weak don't bring them over I got shit to do at noon tomorrow.

BRO 1: never fails always such a fucking pessimistic pete..

Pessimistic Optimist 

It has many meanings such like :
- taking a precaution to prevent a near death experience
- level of optimism
- they see the cup as nor half full or half empty as to them it is constantly filling whilst constantly emptying
- for a good thing to happen a bad must follow and vice versa

our everyday lives are contributed to by pessimists, optimists and pessimistic optimists. An example of this is that : the optimists invent the aeroplane (great invention defies gravity and stuff), then the pessimists come along and think “no I don’t like that” so they come up with the parachute. Hey presto two great inventions one from a hopeful lunatic and one paranoid hopeful. You have the plane but how about the glider? Once again the optimists make them and such the pessimists the parachute. Now who tests it? The pessimist won’t yet as the optimist trusts his handiwork to much he want to go without any safety so the pessimist stops him. Now no one’s testing it. “I know” they think and they go fetch Dave from the local cafe. Everyone say hi Dave...Now Dave is s pessimistic optimist and he loves the idea of just gliding down to earth however he doesn’t want to die if it goes wrong so he takes the pessimist’s parachute. This is one definition of a pessimistic optimist: taking a precaution to prevent death or severe pain.
