“Dasher” is a jazzy tune that can be interpreted as many different things, but most prominently about a reindeer. He makes a girl’s dreams come true and is the “only thing that can help her” as Gerard once stated in a liveshow.

She dreams this reindeer will take her away from her miserable​ job. She wants to get away- she wants to escape! But the only thing that can help her is this motherfucking reindeer.

The track remained unreleased for multiple years until its studio release on December 14, 2018. The track features a spoken interlude and backing vocals from Lydia Night, frontwoman of the band The Regrettes.
