Teenage slang "schiznick/shiz" (= great, cool)--Query

[Steve Kl.]

When I was in NYC in September 2002, every other subway car had giant ads
for some type of breath mint that prominently featured some guy saying "Fa
Shizzle" (for sure) in response to some statement -- so it made its way
into mainstream advertising some time ago.

My friends who teach secondary school in the suburbs used to use it all
the time when imitating or talking about the kids. (and usually in the
phrase "Sizzle my dizzle")

It was my impression that as slang it has already started to become passe,
but I'm not a slang specialist, so that's just based on my perception of
listening to people who are in contact with kids all day.
