Something that is very good or favorable, one might say your favorite. Used as an adjective. Originated from the Chuckle
Sandwich podcast in which Ted Nivison told a story about his childhood stuffed animal “favorite
puppy.” Can also be used in the context of “least favorite
puppy,” which means the opposite.
Person A: It’s my
birthday today!
Person B: Dude, that’s favorite
puppy. I wish I could say the same, my
dog died this week and it was least favorite puppy.
