What is "rubber duckie"

n. (context informal English) A rubber duck (bath toy).

"Rubber Duckie" is a song sung by the Muppet character Ernie (voiced by Jim Henson) on Sesame Street. The song is named after Ernie's toy, a rubber duck affectionately named Rubber Duckie.

The song became a surprise mainstream hit, peaking at #16 on the Hot 100 on 26 September 1970 and nominated for the Best Recording for Children Grammy in 1971 but losing out to the album The Sesame Street Book & Record, which contained the song. The song had follow-ups " Do De Rubber Duck" and " D-U-C-K-I-E" and was the centerpiece of 1988's "Put Down the Duckie", performed by Hoots the Owl but also featuring Ernie.

Little Richard performed a rock-and-roll version of the song as a guest on a 1995 episode of Sesame Street. Jane Krakowski sings the song on her live album The Laziest Gal in Town. The song made a brief appearance in a scene in Three Men and a Little Lady, and during an episode of Whose Line Is It Anyway?.
