Emo vs. Oreos

Alright, listen up, buttercup. You know how emos are all sad and stuff, right? Well, this joke is saying that an emo's barcode gets longer every day. That's a play on words, see? It's like saying they're adding more "lines" to their metaphorical barcode 'cause they're just so darn sad. Bet you think barcodes are only on Oreos. You're so dumb. It means more problems, more sadness, more emo-ness. Get it now, genius?
