when used, 'steez' announces the fact that you care more about what other people think of you, than simply just having a good time thru your own devices.
it is typically used by wannabes, or those who might do one or two runs per day, before poncing about at a near piste bar.
eg.
-'hey yo yo yo, check my monster steez y'all'
-'fuck off wanker'
well that is the euro interpretation anyway.....
