For example:
"You, mate, are an absolute *"
"That's a real *ish attitude you've got there, mate"
Just to add to the fun, the inflection applied to the word 'mate' can change it's meaning from one of jovial familiarity to one of utter disdain.
And even more fun:
"How're you doing, you old *"
Can also be a friendly greeting.
The English language can be so entertaining.
That makes me think of that time where my Australian colleagues greeted each other and one of them said "so, how's old mate doing?".
To me, it sounded like she was asking him how he was dealing with his erection problems.
