"The Ballad of Flammingrad"
Every December we all gather round To pay our respects to a troll so renowned
In remembrance of the friend we had A jolly old soul we called Flemmingrad
We all dig deep down And we uproot the past We shove up its nostril a fistful of grass We shape his likeness, bless his soul Oh, Flemmy the fungus troll
Lyrics from 'Olaf's Frozen Adventure'
What does "past" mean here?
