(a backronym for "sweet, little, unforgettable thing") is a song by American singer Bea Miller.
Hollywood Records released it on October 6, 2017 as a single for her third extended play (EP) Chapter Three: Yellow (2017).
The song's title was expanded to "Sweet Little Unforgettable Thing" in the game, likely to be more kid-friendly.
In an interview with Teen Vogue, Miller said that she was inspired to write the song when someone commented on a picture she posted of herself to slut-shame her.
Miller's co-writer looked up the word 'slut' on the Urban Dictionary and one of the definitions defined it as an acronym for "Sweet, little, unforgettable thing".
