South Korea had a mostly shit World Cup, drawing once and losing twice and looking haggard throughout. So when they arrived home this Sunday, BBC explains, "angry fans threw handfuls of sweets at them, which is considered an insult in the country." BBC does not explain that the candies look like dicks, and throwing them apparently means "eat these dicks."
Here's what the candies look like, as explained by the Ask A Korean blog on Monday:
You can... sort of see it? Insomuch as anything really looks like a dick, sure, those can be dicks.
Here's the explanation from the Ask A Korean post:
This is called 엿 [yeot] in Korean. "Toffee" is a solid translation, because that's what yeot is—it is a candy created by solidifying thin strands of syrup. The insult is to say 엿 먹어라, or "eat yeot." Hm, put this long, sticky thing into your mouth? Wonder what that could possibly mean?
Yeot is a bit more broadly used as an expletive than just meaning dicks, but we don't have time for all that. So! Let's impose that reading onto broader coverage, shall we?
