Steroids. I won't go out into the main night life strips in any Australian city any more because there is too many retarded bodybuilder types on steroids looking for fights. And it's always the worst sub types - middle easterns and southern europeans - because they have such fragile egos and know that they are shit people. But they betray their self belief with the targets they choose - no one that's bigger than them or looks like he can handle himself - they go for the weakest just like school bullies. Of course there is worse - the steroid cocaine combo.
