The line comes from JonTron, the comedy YouTuber Jon Jafari, and his review of Flex Tape, where his enthusiasm for the product spills over into a demand to buy the whole supply. Clipped from that video, the two-second outburst spread through meme pages, reaction videos and soundboards, where fans reused it whenever a purchase went gloriously overboard. Its appeal is the contrast between a mundane shopping decision and JonTron's total commitment, so it still works as a quick shorthand for impulse buying, greed played for laughs and saying yes to everything at once.
