look up any word, like donkey punch:
1.) The girl dreaming is sugarplums in How The Grinch Stole Christmas and starred in We Were Soldiers and Law & Order alongside her older sister Taylor Momsen. She is not currently acting (2011) but goes to school and is living in Maryland with her parents; Michael and Colette.
Person 1: Hey, who is Taylor Momsen's little sister?
Person 2: Oh, Taylor's little sis is Sloane Momsen.
