The line comes from Unknown from M.E., the theme song for Knuckles the Echidna in Sonic Adventure, first released in 1998. Performed as a rap, the track opens by introducing Knuckles as Sonic's tougher, treasure hunting rival, and that opening quickly became its most quoted part. Clips of the phrase spread through gaming videos, edits and soundboards, detached from the full song. Its lasting appeal is nostalgia for the Dreamcast era combined with a perfect short entrance line that Sonic fans instantly recognise.
