It’s dangerous to be breezy with a hothead (5)
I believe the answer is:
Here is my best explanation:
'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 "alarming", "An ape may be", "Perilous", "Armpits can be", "like Esau", "fraught with danger", "triggering alarm", "description of Jacob's brother Esau", "Hirsute - dangerous" and "Dangerous".)
