When you dish out a 죽빵 to someone.

나한테 죽빵 한 대 맞고싶어? (Do you want to get punched in the face?)

방금 준호가 나한테 죽빵을 날렸어 (준호 flew a 죽빵 at me; 준호 punched me in the face.)

어제 싸우면서 죽빵 한 대 갈겼어 (I landed a 죽빵 last night in a fight.)

I love comic books. These are great to wind down a busy day with, because you don't have to do a lot of work to enjoy them. No need to imagine the scenes in my head, because they're already drawn in. And there is something inherently funny about the onomatopoeia that get used in comic books. I would never say "KAPOW" or "BLAM" or "ZAP" in real life, but I kind of wish that everyone would start using these words more often, because these words are so lively and full of dynamic energy, with a touch of vulgarity.It turns out that the Koreans are actually better at using these words in real life. Sure, they shouldn't be used in formal settings. But to me, these words add a bit of slapstick spark to our lives when they do get used.Here are a couple of Korean onomatopoeia that you will see in comic books, or 만화.First is the word "주욱," which you might recognize better by its variations such as "주우욱," "주우우우욱," "쭉," "쭈욱," etc. This word means to reach out. For example, if a cartoon character was stretching, there might be the word "주욱" written in the background. Since you're reaching out, it sometimes makes sense to write out the longer version of the word such as "주우우우우욱" to describe the length of the stretch and the reach.This word also gets used in everyday Korean, in contexts such as "주욱 뻗은 길" meaning "the (straight) road that stretches way out," or "쭉 뻗은 나무" meaning "the tall (straight) tree."The second onomatopoeia doesn't need a lot of explanation; the word is "빵." Although I have just said that "빵" is an adjective for well-inflated objects, there is one other meaning for it. When you hit someone, "빵" is the sound you make.So when you use these two words together to create a new slang "죽빵," first of all, it is vulgar (not in a profanity type way, but in the comic-book informality), and it means that you are reaching out (죽) to hit (빵). Well, when you reach out to hit, you usually end up punching people squarely in the face. It's slightly entertaining that you can count these things, and the unit of count is "대." So one 죽빵 is "죽빵 한 대," and two 죽빵 is "죽빵 두 대," etc.Remembering that we are using a comic book-style word, so whenever you use it, it's definitely going to be funny. So it's used mostly in an exaggerated way. For example, if your little brother is being annoying, you might threaten him by saying:If your friend 준호 accidentally hit you in the face, you might rant to your other friends about how you got beaten up by your friend by saying,If you got involved in a bar fight, and managed to get in a good one before you got broken up, you might later brag to your friends by saying:Note that various verbs describe the act of landing a 죽빵. As it was never a proper word to begin with, you can choose the verbs that seems to go well with the context. Even if it were not used previously, if the Koreans agree with you that the verb was appropriate, maybe it'll even catch on! As always, the important thing in Korean internet slang is to experiment, and to be creative.
