Gain detergent's ads tout closeness. Well, how close would you stand to someone whose clothes were washed in Barf? The word means "snow" in Farsi, and apparently the product is quite popular in the Middle East. Its cult appeal is also growing online, where product shots and one-liners spew forth like giddy projectiles. Is it the worst brand name ever? In places where Farsi's the dominant language, clearly not. In English, however, it presents possibilities for scandalously sophomoric wordplay rivaled only by the spicy Caribbean chicken bullion known as Cock Soup.
