Neo got my back
An iconic line in the well-known intro song "Intro: Neo got my back" by South Korea's kpop group NCT U; the 1st and main unit of NCT owned by SM ENTERTAINMENT.
Whenever I told my friend that I had her back, she would always reply loudly with "Neo got my back, culture thing, tech tech on my mind" so I searched it up. Turns out it was a song all along and I have discovered that now any phrase can be turned into a kpop reference.
