Why do I need to know the word
foncedé
?
Because we've all partied a little bit too hard at some point.
What does it mean?
Foncedé
, pronounced 'fons-day', is the verlan form of
défoncé
: 'fucked up'.
It is an adjective you would use to describe a state of inebriation - typically after drinking or, for the real degenerates among you, perhaps something a little harder.

Lorenzo, an endearingly terrible French rapper, makes extensive use of the term in his song
Fonsdé Toute La Nuit
(Fucked-up all night). Note the incorrect spelling of
foncedé
in the song's title - he must have been very drunk indeed.
