Poke fun, you said, pinching wide bottoms (5)
I believe the answer is:
nudge
'poke' is the definition.
(I've seen this before)
'fun you said pinching wide bottoms' is the wordplay.
'bottoms' indicates one should take the final letters (I've seen 'bottoms of' mean this).
The final letters of 'fun you said pinching wide' are 'NUDGE'.
(Other definitions for nudge that I've seen before include "Encouraging prompt" , "Jogger" , "Gentle poke with elbow" , "Dig with elbow" , "Remind (with the elbow?)" .)
