Yeah "geler la face" is more or less a way to say he got stoned, or high on drugs. In french when we say somebody is drunk there is an expression saying "Il est rechauffer" wich mean he is warm in english. For drugs its "il est geler" or he is cold if you translated literally, but i never seen "cold" used in english for drugs, its stoned or high. But its a very common expression in quebec. Dunno if its region only, i always lived near where i live now exept a short stint in Mont-Tremblant.
As for my cousins friend, its only weed tough,

so he is not really a junky if we can say lol.
And a little note since i am on topic...
Tonight owner showed up again, no 24 hour notice, wanted to repair the toilet. Actually it was not really broken, its just we had replace the chain by a tie wrap... but the futur owners tried it for some reason last time and mentioned it was "long to flush"

so i guess he had to put back a chain to look better In any case i don't mind him doing so, it just piss me off he won't even call... I mean what is it to at least fucking call.. to make sure we are home, to make sure he is not... you know... BOTHERING US... Fucking dude seem to not even know the rules...
