a pony
A pony is basically anything good. Like, if you're eating a burger and it's amazing, it's a pony. If you're eating a sandwich and it's just okay, it's not a pony.
This burger is a pony, I'm eating it and I'm happy
This sandwich is not a pony, I'm eating it and I'm sad
This pizza is a pony, I'm eating it and I'm thrilled
