courageous readiness to fight or continue against odds : dogged resolution
I like this use of pluck. Sounds so feisty! I think of a small, wiry fellow in a rigid hat as he strides down the street itching for a fight. Turn-of-the-century maybe, watch fob dangling.
Upon first reading the daily prompt today I immediately thought of eyebrows. Then chickens. Not that the two belong together, although chickens plucking eyebrows would be rather funny. 🙂
