Beurette : feminine of "beur" Inverting syllables, "arabe" (arabian or better north-African or maghrebian) became "rabe" then rapidly "rebeux" (still used). Then inverting once again letters, "rebeux" became "beurs" and eventually "beurette" for girls.
You wild find French Maghrebian girls in usual escort sites, but not so many practice escort. There used to be French Maghrebian girls at the boulevard Soult in Paris, 15 years ago but they stayed away from troubles by police officers.
