The line comes from Ultrakill, the retro first-person shooter where V2 is a rival boss built as a newer model of the player character V1. Their fights are built around speed, parries and stolen weapon arms, which is why an arm joke works as a direct threat between two machines. Clips of V2 encounters spread through gameplay videos, boss compilations and fan edits, and this single taunt was cut out on its own because it sums up V2's arrogant personality in under four seconds without needing the full fight for context.
