The line comes from Hololive VTuber Laplus Darknesss, known as La+, whose playful, energetic delivery made the phrase a favourite among fans. Short clips of her streams are often shared as soundboard memes, and this encouragement for Wifi-kun spread through gaming videos, livestream highlights and anime edits where a bad connection needed a light-hearted response.
