A term that can be used to replace any profanity in a cheerful yet meaningful manner, it is mostly appropriate when a profanity must be shouted. It is also often used when everything is going against you but you simply don't give a shit and is in this case expressed in the song; 'cunt and onion, cunt and onion, tra la la la la'
playing FIFA and someone scores against you:

'oh cunt and onion!'

or

Your life's going to shit, the wife has left and you lost your job

'cunt and onion, cunt and onion, tra la la la la'
