It’s dangerous to be breezy with a hothead (5)
I believe the answer is:
hairy
'it's dangerous' is the definition.
(I've seen this before)
'breezy with a hothead' is the wordplay.
'breezy' becomes 'airy' (I've seen this before).
'with' is a charade indicator (letters next to each other).
'a hothead' becomes 'h' (head letter of 'hot').
'airy' put after 'h' is 'HAIRY'.
'to be' is the link.
(Other definitions for hairy that I've seen before include "Frightening - like a bear?" , "Hirsute - dangerous" , "An ape may be" , "Armpits can be" , "Having shock" .)
