Nitrogen Crown

A person who feels/thinks/ or is in a position of power but indulges in the feeling of greatness from it. These people get absolutely arrogant and become such assholes with their feeling of power that they belittle others and overestimate themselves. In other words, they're selfish delusional pricks with imaginary crowns on their heads.

Another way you can say this is: Crown Of Nitrogen

Person 1: These dickheads in my class won't stop bothering me, they think that they rule the fucking world just because they're part of the student council.

Person 2: Don't listen to those fuckwits, they think peaking is cool but high school is temporary, their position of being a student council won't matter anymore. All they have on their heads are nitrogen crowns, they think they're kings but they're not.

Example 2:
Person 1: These dickheads in my class won't stop bothering me, they think that they rule the fucking world just because they're part of the student council.

Person 2: Don't listen to those fuckwits, they think peaking is cool but high school is temporary, their position of being a student council won't matter anymore. All they have on their heads are crowns of nitrogen, they think they're kings but they're not.
