hello? #JOHNNY #NCT #NCT127

In the Korean comments

One top comment reads, in translation, “From the middle on, he’s basically charging straight in.” Another escalates the collision joke: “If it’s Johnny doing the body-checking, I’d gladly take the hit.”

What the words mean

몸빵 (mombbang, taking a hit with one’s body) literally evokes using the body to absorb or deliver an impact. Here, “Johnny’s 몸빵” (mombbang, taking a hit with one's body) turns the apparent collision into playful, exaggerated fan language: the commenter is saying they would willingly be on the receiving end.
