Verlan is usually used by french people with North African origins (where Arabic is the official language)

I have always thought that these people were just reading French from right to left like you would read Arabic, giving birth to Verlan.

There are no vowels in arabic, so "bi" "ba" "bo" are just instances of the letter "b", which I thought explained why verlan reversed the words but kept the order for each "consonant+vowel" unit
