The line comes from The 7th Guest, the 1993 horror puzzle adventure released for PC that helped popularise full motion video and CD-ROM gaming. Set inside the mansion of toymaker Henry Stauf, the game taunts the player throughout its puzzles, including the maze section where this lonely remark lands. Clips from the game later circulated on soundboards and in retro gaming videos, and the phrase survived because it sums up Stauf's mocking tone in a few seconds while fitting any modern clip about being left alone.
