Amber of f(x) posted a funny picture of her and her labelmate BoA earlier today. She amused her fans by posting a tweet, "I woke up at 2am and decided to text BoA since it's been a while... oh dear...keke" She attached a photo along with it, which happened to be the screenshot of the message. In the photo, Amber wrote "yo nuna just wanted to text ya saying i miss ya!" and BoA made quite an amusing reply, "haha don't say you're drunk.." 

Internet users had noticed that Amber used the wrong term by calling her "nuna" when she should have called her "unni". They commented, "I love how Amber calls BoA nuna!" "Oh Amber you're so funny" and "This is too funny"
