Speedy Mo! (7)

Ross

I believe the answer is:

instant

I believe this is a double definition.

'speedy' is the first definition.
(thesaurus)

'mo' is the second definition.
(both can mean a short period of time)

(Other definitions for instant that I've seen before include "Occurring immediately, like some fast food" , "A second - coffee, maybe" , "Jiffy" , "Fast, flash" , "like some coffee?" .)

I've seen this clue in The Telegraph.
