Are ye starting are ye?
Literal translation: "Are you instigating man-to-man combat?" It can sometimes be taken as an invitation to combat.
Gurrier: "Smella benjy off yer moth!" Skanger: "Ye startin' are ye? Go hang yer bollix off de five lamps!!!"

Ah, the post has arrived, and so have you. Would you like me to translate 'Are ye starting are ye?' in use for you?
'There is a frightful odour emanating from your mouth!' 'Are you seeking a quarrel, sir? Kindly go and hang your testicles from the Five Lamps!'
Any good?
