Cheeky for example grabbing seconds (5)
I believe the answer is:
sassy
'cheeky' is the definition.
(I've seen this before)
'for example grabbing seconds' is the wordplay.
'for example' becomes 'say' ('say' can be used to introduce an example).
'grabbing' means one lot of letters goes inside another.
'seconds' becomes 'ss' (an abbreviation for seconds written twice).
'say' going around 'ss' is 'SASSY'.
(Other definitions for sassy that I've seen before include "Cheeky American" , "(In US) saucy" , "Bold, spirited, cheeky (Amer.)" , "Impertinent (US colloq.)" , "Pert" .)
