Niero is the highest in the heirarchy of the word cool. Niero is more zoomer and not as Boomer as saying "cool". Neiro is not to be confused with "neat-o" and is not to be used as a conversation ender a boring conversation filler.
Example 1: Damn LaurieAnn, did you just peep that last ep of live PD? It was Niero.

Example 2: RoeB.Wade, want to go play golf of this new Niero ass course downtown?
