The phrase comes from everyday Spanish, where yo te lo voy a regalar means I am going to give it to you as a gift, and the vua spelling preserves how the line is heard in the clip. That small mispronunciation helped the recording circulate as a short meme audio on soundboards and in chat shares, separate from any confirmed original video or creator. It stays popular because the meaning is understood even by non Spanish speakers from context, and the short length fits reaction edits, gift jokes and ironic giveaways perfectly well today.
