Boofhead cheer for trunk? (4)
I believe the answer is:
bole
'trunk?' is the definition.
(I've seen this in other clues)
'boofhead cheer' is the wordplay.
'boofhead' becomes 'b' (head letter of 'boof').
'cheer' becomes 'ole' (I have seen 'Spanish cheer ' mean 'ole' so perhaps 'cheer' could also mean 'ole').
'b'+'ole'='BOLE'
'for' is the link.
(Other definitions for bole that I've seen before include "Tree trunk" , "Tree-trunk" .)
