'eritrea presumably it'll form part of a suit in bermuda' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'unable to pay for endless fish on boat' is the wordplay.
'unable to pay' becomes 'short' (I've seen this in another clue).
'for' becomes 'to' (eg both can mean 'in the opinion of').
'endless' means to remove the last letter.
'fish on boat' becomes 'rousers' (I can't justify this - if you can you should believe this answer much more).
'to' with its last letter taken off is 't'.
'short'+'t'+'rousers'='SHORT TROUSERS'

'around' acts as a link.
