3ala means (on) in Arabic
we use the number 3 because the letter (ع) does not exist in English so we use those number in chat language.
and it written in Arabic this way : على
I think it is an RAF slang word for "he's not bothered" or "uncaring".Possible Arabic. Hope this helps If it is Arabic, it would be a form of 3ala keyfek (على كيفك) which is a Lebanese expression that roughly means "what's up".
