Feminine anger about foul-smelling resin (12)
I believe the answer is:
Here is my best explanation:
'resin' is the definition.
'feminine anger about foul-smelling' is the subsidiary indication.
'feminine' becomes 'f' (abbreviation listed in Chambers).
'anger' becomes 'incense' (incensing is a kind of angering**).
'about' is a charade indicator (letters next to each other).
'foul-smelling' becomes 'rank' (I've seen this before).
'incense' after 'rank' is 'rankincense'.
(Other definitions for frankincense that I've seen before include "One of the Magi's gifts", "present at birth", "Birthday gift", "gift second to gold?", "Gum resin used as incense", "Aromatic gum resin - an original Christmas present!", "One of the gifts of the Magi", "Source of pleasant scent", "Christmas gift" and "Nativity gift; aromatic tree resin".)
