Place large letters after spinning dice (3,2)
I believe the answer is:
cut up
'dice' is the definition.
(I've seen this before)
'place large letters after spinning' is the wordplay.
'place' becomes 'put' (synonyms).
'large letters' becomes 'uc' (upper case).
'after' means one lot of letters go next to another.
'spinning' says the letters should be written backwards.
'put'+'uc'='putuc'
'putuc' backwards is 'CUT-UP'.
(Other definitions for cut up that I've seen before include "Extremely upset" , "Miserable" , "collage" , "Dissect" , "Happy? No" .)
