'ready for dropping off in durham?' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'southern ladies' brother' is the wordplay.
'southern' becomes 's' (abbreviation).
'ladies'' becomes 'loo' ('the ladies' is a type of loo or toilet).
'brother' becomes 'my' (both are expressions of shock).
's'+'loo'+'my'='SLOOMY'
