Right Behind You comes from the Team Fortress 2 soundtrack released by Valve, composed by Mike Morasky as the theme for the Spy, the French stealth class introduced with the game in 2007 who disguises himself and kills with backstabs. The track became a staple in TF2 frag videos, GMod animations and Source Filmmaker shorts before spreading to general meme edits. Its title works as the punchline itself, so creators reuse it whenever someone sneaks up unseen, keeping the cue recognisable far beyond the original game community.
