Perhaps a Floridian can? (8)

Ross

I believe the answer is:

restroom

I'm a little stuck... Click here to teach me more about this clue!

'perhaps a' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'floridian can?' is the wordplay.
'floridian' becomes 'rest' (I can't justify this - if you can you should give a lot more credence to this answer).
'can?' becomes 'room' (can is a kind of room).
'rest'+'room'='RESTROOM'

Can you help me to learn more?

(Other definitions for restroom that I've seen before include "Where some may have recovered" , "John" .)
