Why K-pop has its own slang

Many of these words started in Korean and were picked up by international fans, like daebak, aegyo and selca. Others are English words that fandom reshaped, like bias, which lost its negative meaning and became a simple way to say “favorite.” Because fans talk across languages every day on social media, this mix of Korean and English spreads quickly and changes fast.
