Let it die who's with me
Let it Grow is a song from the 2012 animated movie "The Lorax". In this song, all the townspeople sing along and want the seed to grow.

Let it die, let it die!

This was another meme from this song where the evil mayor Alyosius O'Hare sings that he wants to destroy the seed. Then his employee Cy tells him he's a greedy dirtbag.
