My personal three favorites will always be

'Oh whoa whoa that's no no, boy, no no no'

'Chogiwa danbeone neukkyo'

'Ppappappira ppappappira ppa'

But there's a lot more

'New generation is back, yeah we killin this track right now'

(Actually every Ravlish attack)

'Black Pink in your area'

The entire Fantastic Baby and Bang Bang Bang tbh

'I need therapy lalalalala therapy'

And of course we can't forget 

'It's been a while

But I'm back again right now

These are new pants (?)'

Boy, I think I messed that up. I haven't listened to that song in a while.
