"Bo le lavabo (WC Kiss)" is a 1990 novelty song recorded by the French TV presenter and humorist Lagaf'.

In one of his sketches, French humorist Vincent Lagaf' (Vincent Rouil), who featured on several TV programs in the 1980s and 1990s, commented on how easy it was to produce a hit single during the house period, as the repetitive music distracts the audience from the words, reduced to a bare and trivial content.

[2] In France, "Bo le lavabo (WC Kiss)" debuted at number 40 of the chart edition of 24 March 1990, then climbed regularly on the chart and eventually reached number one in its 13th week, dislodging Elton John's hit "Sacrifice", but was replaced the next week at this position by Zouk Machine's summer hit "Maldòn' (la musique dans la peau)".

The single was certified Gold disc by the Syndicat National de l'Édition Phonographique, the French certificator, for 400,000 units.

[3] On the European Hot 100 Singles, "Bo le lavabo (WC Kiss)" charted for 24 weeks, nine of them in the top 20.
