If you think about it the song “Let It Go” takes on a different meaning if you’re singing it while having to go to the bathroom.
Let it go, let it go
Can’t hold it back anymore
Let it go, let it go
Turn away and slam the door
I don’t care what they’re going to say
Let the storm rage on
The cold never bothered me anyway
I know they have parodies, but you don’t really need to change any words.
