Speedy Mo! (7)
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?" .)
