ok i was reading this audiobook andsome of these words came up "j’y pige que dalle , pauv tache, poser un lapin i cannot understand them
j’y pige que dalle = j’y comprends rien = I don’t understand anything of this
piger, capter = comprendre ; que dalle, que tchi = rien
Pauv’ tache = pauvre tache = abruti / idiot = you moron
poser un lapin = to stand someone up
The first two are slang, the last one is an idiom.
