Junkrat is one of the original heroes in the team shooter Overwatch, released in 2016, an Australian demolition expert known for traps, grenades and a chaotic sense of humour. The 'I need healing' line is one of the game's built-in communication calls, used by players to alert healers when their health is low. Outside matches it became a running joke in Overwatch clips and streams, especially when the hero asking for help had just blown himself up, and it remains popular as a short reaction sound for gaming edits.
