I'll add the two I had to have explained to me:

chèm <- moche (ugly), not to be confused with chanmé <- méchant (bad) (think bad motherfucker), whose ending can't affort to drop.

reuch <- cher (expensive), not to be understood as an anglicism for "rush".

> chèm <- moche (ugly)

You'd write it cheum (moche => cheu-mo => cheum')

[tripa]

I've only ever heard is as chèm, so that's how I'd write it.

Sorry, I meant "it's written cheum"
