The line comes from Overwatch, Blizzard's team-based hero shooter first released in 2016, where Junkrat is a playable damage hero obsessed with explosives. RIP-Tire is the name of his ultimate ability, which lets him drive a remote-controlled spiked tire into enemies before detonating it, and he shouts the line as the ability activates. The clip spread through gameplay videos, streams and meme edits, where its gleeful delivery became shorthand for an incoming explosion. It remains popular because it is instantly recognisable to players and works as both a warning and a joke.
