Short text about Mike's stint (6)
I believe the answer is:
scrimp
'stint' is the definition.
('scrimp' can be a synonym of 'stint')
'short text about mike's' is the wordplay.
'short' means to remove the last letter.
'text' becomes 'script' (I've seen this before).
'about' indicates putting letters inside.
'mike' becomes 'm' (phonetic alphabet: alpha, bravo, charlie etc.).
'script' with its last letter taken away is 'scrip'.
'scrip' placed around 'm' is 'SCRIMP'.
(Other definitions for scrimp that I've seen before include "Be economical, mean, with" , "Treat stingily" , "Skimp, stint" , "Be frugal and sparing" , "Watch the pennies" .)
