al-box
n.— «Seventy-eight fully grown men were fit in two police cars with the capacity of each only 10. Many Egyptian university students must know those cars quite well—they are referred to in Egypt by an English word borrowed into Arabic specifically for this usage: “al-box.”» —“Real life can be even stranger than fiction” by Tamim al-Barghouti Daily Star (Lebanon) Sept. 14, 2004. (source: Double-Tongued Dictionary)
The word al-Box refers to any box. If it didn’t, how would it make sense to non-English speaking Egyptians?
