Davie504 is an Italian bassist and YouTuber known for slap-bass videos, bass battles and playful challenges, and his fans are affectionately called slappers. The greeting became his trademark opening, repeated at the start of his videos until viewers associated it with his energetic, community-driven style. As clips of his intros circulated in edits, memes and short videos, the phrase travelled beyond his channel and became a shorthand greeting among bass fans online, still used today to signal a bass-themed joke or cover.
