Krooz (sic) is the barry spelling of cruise, meaning a meet, usually on an evening where barryboys meet up and rev their car engines, try to do burnouts, donuts and handbrake turns.
Kroozes generate lots of noise and are generally antisocial.
The police usually get involved and barrys tend to drive off very quickly to another location.
Mate, are you going to the krooz tonight?

I've built this new internet krooz website and i'm going to be an admin!
Kroozer, a person who enjoys less than leisurly drives during their free time. Will be found during the day fitting blue pipes into their engines and applying a tinted stickyback plastic to their windows. By night they can be found driving people around in exchange for loose change, similar to a taxi service but ariving faster and taking no responsibilty for injury to passengers (normally four crammed in a back seat).
