The comparative form of feisty; more energetic, spirited, or inclined to be argumentative.
From 'feisty' (itself from 'feist'), plus the comparative suffix '-er.' The adjective 'feisty' became popular in the early 20th century to describe something full of spunk or liveliness.
Interestingly, 'feisty' was almost exclusively applied to women in mid-20th century writing, but modern usage has made it gender-neutral—showing how language evolves to become more inclusive!
