"Lipgloss" is a song by British rock band Pulp, from their 1994 album His 'n' Hers. It was released 12th November 1993 as the second single from the album, charting at #50 in the UK Singles Chart (see 1993 in British music).
The lyrics are about a woman who cannot seduce her boyfriend anymore because she has "lost her lipgloss". This appears to be a metaphor for losing 'it', her sex appeal.
