Terroriser, real name Brian Hanby, is an Irish gaming YouTuber known for his work with the VanossGaming group and for dry, blunt commentary in multiplayer videos. Coomer is internet slang for someone obsessed with pornography, popularised in meme culture as a shorthand insult for excessive thirst. Short clips of streamers saying the word spread through soundboards and gaming edits because the single-word delivery works as an instant label. Fans still reuse this version because Terroriser's voice makes it recognisable without needing any context from the original stream.
