Untervention

unnerfed 

Comes from the online slang: "to nerf" (--> weaken a specific item, because it is or has values that led to an unbalance and had to be reduced).
Unnerfed is the opposite which means that the item is not weakened.
Example:

Soul Sword v.1.03 100 Damage
Soul Sword v.1.04 90 Damage

This item is unnerfed.

They need to nerfe this gun, it is too over powered.

unnerved 

Describing an ongoing state of wretching, vomiting and self-loathing due to adolescent humiliation by a severe, sexually-frustrated 70-year-old English teacher at a 1960s private girls' school in Cleveland, Ohio, who stated that the word "unnerved" did not exist.

It does now. Look it up, bitch.

Forty-five years later, "Zero for the Day, Arms" found the nerve to define "unnerved."
