They could describe everything with one single word
You know? Like

Boba tea (gnarly)
Robotics (gnarly)
Fried chicken (gnarly)
Partyin' in the Hollywood Hills (uh)
This song (gnarly)
Oh my God, that new beat (gnarly, freaking gnarly)
Oh my God, is this real? (Gnarly, everything's gnarly)

Oh, we're in a session tonight, gang, gang
Oh, we're going out tonight, gang, gang
Oh my God, this song's so lit, congratulations
Now you be like: Gang
Gang, gang, gang, gang, gang (haha)

Gnarly
Gnarly
Everything's gnarly
Na-na-na-na-na-gnarly (gnarly)
Na-na-na-na-na-gnarly (gnarly)
Na-na-na-na-na-gnarly (gnar-gnar-gnar-gnar–)
Everything's gnarly
