Depends on the "lingo" invovled.
"Ebonics" or "Street talk," on the other hand, is something I'll generally ignore. While it may be irksome to someone who walks up to me on the street, simply giving them a blank look until they phrase their query properly usually suffices (it also worked on my two boys.) I didn't bother with that nonsense when I was a teenager myself - and I see no reason to start now...5-90
