Zebda (زبدة, transliterated Zibdah), the Arabic word for butter (beurre in French), is a play on the word beur, a French slang word referring to French citizens of Arab origin—several of the group's members are of North African and other immigrant descent. As Zebda was originally formed for a community organization and many of the members met through social initiatives and activism, the band remained highly political throughout its existence; Bruce Crumley of the Culture Kiosque has called the group "politically engaged and culturally committed" and "politically progressive."
