A Banh-rab is an Arab who resides in and/or has been influenced by Cajun culture, primarily the Cajun dialect.
"Banh" is a phonetic spelling of a common sound uttered by Cajuns before expressing an explanation or reaction during a spoken conversation.
"Did you see dem Banh-rabs at dat crawfish boil, dare? Dem bahn-rabs was suckin da heads off dem mudbugs!"
(Did you see those Arab-Cajuns at the crawfish boil we had? Those Arab-Cajuns were really enjoying the crawfish there.)
"Dass da LASS toime I get gas by dem Banh-rabs, dass a rip-off, yah!"
(That is the last time I purchase gasoline for my automobile from an Arab-owned gas station in southern Louisiana, their prices are a rip off!)
