“Ppl knocking each other off lol,” quips the nonchalant Instagram bio of the account @diet_prada. An angry undertone is palpable in the account’s ironic humor, however. The owners of the account, and the 1.1 million users who follow it, have had enough. Diet Prada has been popularized — and trademarked, according to the account’s name on Instagram — as a term referring to knockoffs in fashion. Within the account, a garment that resembles Prada is exposed as a cheaper rendition that leaves behind a toxic aftertaste.
