Fool getting second wind (5)
I believe the answer is:
twist
'wind' is the definition.
(I know that wind can be written as twist)
'fool getting second' is the wordplay.
'fool' becomes 'twit' (both can mean a stupid person).
'getting' is an insertion indicator.
'second' becomes 's' (common abbreviation).
'twit' enclosing 's' is 'TWIST'.
(Other definitions for twist that I've seen before include "Spiral" , "Distort - dance from the 1960s" , "Wind spirally" , "Deal card face upwards" , "Distort; apply torque" .)
