Commonly used abbriviation in Belfast, and the 'Duff'.. meaning 'get her bucked'. This is what we like to say to a girl that is 'great' or 'sexy'.
Also a term used meaning 'get him banged', this would usually be said to some cunt.
Mark & Ross were sauntering 'round town and saw a hot girl, they shouted "GHB GHB.. get her bucked! Eyeooooo!!!"
Later that day they seen a ginger cunt, and laughed at his funny coloured hair, the ginger cunt started to slabber at the two, so they shouted "GHB" this time meaning 'get him banged'
