Roumi (or roumia for feminine) is a Moroccan Arabic word used to denote foods, animals, clothing and other things which are non-traditional, imported or of Western or European influence. It is often used in contrast to, or to denote opposite meaning of, the word beldi, which means "traditional" or "indigenous."
Homemade Moroccan butter, for example, will be referred to as zebda beldia while imported European butter is called zebda roumia. Free range chickens are called djaj beldi while factory raised hens are called djaj roumi. Likewise, traditional Moroccan cookies will be labeled beldi to differentiate them from European roumi style cookies. Even a mongrel dog which has domestic breed characteristics might be referred to as roumi.
