Negative Nancy 

A nickname given to a guy or a girl who always has a negative spin on things. Always brings the mood down with the doom and gloom analogies.

Jack: Way to go Billy...a grand slam!
Tom: God, it's about time he only struck out the last four at bats.
Jack: Just shush and quit being such a Negative Nancy and be thankful it wasn't a fifth strikeout, but it was a grand slam.

Negative Positivity 

1. It is when you do not want something good to happen but are expecting better things to happen

2. Deny a positive way of thinking to the profit of another neutral way of thinking

"Hey do you want to go with me to donate to charity next saturday?"
-"I do but there might be an important event about health & sanitation next week. I just hope it doesn't fall on a saturday or gets cancelled if it is so I can go with you! It's a negative positivity way of thinking!"

negative frequency 

This is the frequency at which the human mind subconsciously thinks. This can be heard and detected by some. This frequency happens before time equals zero, as does a thought happens before time. Negative time and negative frequency are inversely proportional by the formula:
-Time=1/-Frequency.
Where Frequency and Time can be real and imaginary.
This frequency cannot be detected by many frequency detecting devices. It can also be known as a subconscious negative signal.

At that instant moment in time I reacted, I must have been thinking at a negative frequency to react so quickly.
While I was sleeping, my mind was thinking at a negative frequency.

Negative Reinforcement 

A form of learning where a subject is rewarded for desired behavior by the removal of a negative, such as pain, hunger, or a distressing noise. This term is often confused with punishment, which is the introduction of a negative (the punishment) to discourage behavior.

Negative Reinforcement is the removal of something bad. Punishment is the introduction of something bad.

Negative Reinforcement: "Good behavior" in the prison system, where the negative (prison time) is reduced as a reward for not causing problems.

In comparison, the original prison sentence itself is punishment - a negative introduced to discourage behavior.
