Translation:Let's catch the whale!
"Catching the whale" is a Korean expression for circumcision. Most Korean boys get this done at around 12 years old an this is what the kids say. i.e. Jin is absent today because he's catching the whale.
Right. Fortunately more and more parents are aware of its harms and choose not to get their kids circumcised nowadays, and my parents decided not to catch mine. Thanks mum and dad! -blows a kiss-
Is this sarcasm? We don't want to know how to say Let's catch a whale! Why the ❤❤❤❤ not?
