This is a lesser-known electronic-pop song by Spears. Although the song could be about an exclusive club, it is most likely about anal sex.

Imogen Heap sings on this track, which she wrote with Guy Sigsworth, who produced it. Sigsworth got the song (with Heap's vocals) ready for Spears so she could record it at the same time she put down tracks for "Everytime," which he also produced.
