"Her Words Destroyed My Planet" is a song by American rock band Motion City Soundtrack, released on December 1, 2009, as the second single from the group's fourth studio album, My Dinosaur Life (2010).

[1] The song follows past singles such as "The Future Freaks Me Out" and "Everything Is Alright" with quirky, pop culture-referencing lyrics masking personal introspection.

[1] Pierre considered it the most honest song written for My Dinosaur Life.

"I think this is kinda the quintessential Motion City Soundtrack song," said producer Mark Hoppus.

[4] Alternative Press considered the song the album's finest, calling it "an emotionally devastating track about an attempt to win back a former lover that could be the psychic sequel to Weezer's 'Across the Sea'.
