The line comes from the Quake series by id Software, most famously Quake III Arena released in 1999, where an unseen announcer judged multiplayer performance with short awards. Impressive rewarded accurate shooting and became one of the most quoted calls alongside Excellent and Humiliation. As frag movies and later YouTube montages spread, players ripped the announcer lines for use outside the game. Its formal, overblown praise survived because it works both sincerely for great plays and sarcastically for minor achievements in modern gaming videos.
