It was released initially as a promotional single and later released as a single. The song was written by Steve Mac and Priscilla Renea and was the only song in the album without Carpenter's writing credit. The song was the last recorded for the album, Carpenter says. "We'd finish the album, I then heard "Thumbs" which gave me these vibes of fame and black and gold and just like some of my favorite soulful songs."^[1] The song talks about embracing individuality and escaping mediocrity. She says that if people are falling into the same mistakes they are going to continue 'twiddling them thumbs', thus continuing to live in the mediocrity. Carpenter describes the other songs on the album as "children" of "Thumbs".

The music video, which was directed by Hayley Young,^[3] was uploaded to Carpenter's Vevo account on YouTube on February 10, 2017.^[4] The video is set in a New York City Subway car and is shot in one take. The video features Carpenter singing the song with several bored people inside the subway on a typical big-city daily commute. When the idea of the video was being processed, Carpenter thought of a subway because it's where different people would be found; the line "Somewhere in the world" represents those people.^[5]

Brittany Goldfield Rodrigues of Andpop said "the jazzy vibe of this song sold us, and the scatting just made us play it on repeat. With this tune Sabrina really makes us fall for her unique jazz vibes she sprinkles into her pop sound."^[6]
