Por Poquitooo comes from the everyday Spanish phrase por poquito, meaning by a tiny amount, stretched online into an exaggerated reaction cry. Short clips with this delivery spread on soundboards and in meme edits because the meaning is clear even to non Spanish speakers from the tone alone. It is now used far beyond its original context, paired with sports near misses, gaming fails and everyday almost moments, where the drawn out ending has become the recognizable joke.
