The Round 2 call comes from Mortal Kombat, the long-running fighting game series created by Midway, where a deep announcer voice opens each stage of a match with Round 1, Round 2 and Fight. Clips of the announcement spread through gameplay uploads, tournament highlights and meme edits, where creators reuse it far beyond fighting games. It endures because the delivery is instantly recognizable and turns any second attempt into a dramatic rematch, giving ordinary videos the energy of an arcade showdown.
