The line comes from the Brazilian Portuguese dub of the Pokemon anime, where Ash Ketchum says Pokebola, vai whenever he sends out a Pokemon in battle. It is the local version of his English catchphrase Pokeball, go, and Brazilian fans grew up hearing it on television broadcasts and later sharing it online. Short clips spread through meme pages and soundboards because the delivery is so recognisable, and nostalgia for the series keeps it in use for gaming videos, edits and jokes about catching anything.
