There are some occasions when people use the expression "XX ans aux chanterelles" (the most famous one being the "papa smurf" which "a eu 542 ans aux chanterelles"). I was wondering where the expression comes from and it it has any specific meaning.
More precisely, my question are:
- is it just an embellishment? are there any actual difference between saying "J'ai eu 42 ans" ans "J'ai eu 42 ans aux chanterelles".
- is the expression prior to the smurfs?
- does it refer to late summer/early autumn ( mushroom season)
