The line comes from Portal 2, Valve’s 2011 puzzle game, and is delivered by GLaDOS during the sequence built around Cave Johnson’s memorable lemon rant. The scene became widely quoted among players because it combines Cave’s escalating anger with GLaDOS’s unusually passionate agreement. Short excerpts later circulated through gaming videos, reaction edits, soundboards, and meme compilations. The quote remains useful because its meaning is immediately readable as loud encouragement, while the unexplained emphasis on lemons adds a layer of absurdity.
