The soccer squad was pelted with toffees as they arrived at Incheon International Airport near Seoul after arriving home without a World Cup win in any of its three games in Brazil.
According to the Guardian, "go eat a toffee" is an insult in South Korea which is comparable to "get lost" or "screw you." (Good thing the phrase isn't "go eat a bowling ball.")
"I am sorry that we weren't able to return the love and support shown by our people during the World Cup," South Korea Coach Hong Myunbg-bo told the Korea Herald. "It was due to my deficiency as a coach that we didn't put up the desired results. But our players all have a bright future ahead and not everything was lost from this tournament."
The president of the Korea Football Association will be meeting with Myung-bo "within this week" to discuss the coach's status.
After two losses and one draw in the World Cup, Myung-bo is facing pressure to step down even though his contract extends through the Asian Cup tournament in January.
"Firing the head coach based on poor results isn't always the best course of action," said an anonymous KFA official. "President Chung will sit down with coach Hong for some candid talks."
