When you say "ah that's patty" you basically
mean that something is really
epic and/or pleasing/ makes you feel good.
For example; when you're on the same wavelength with someone, are somewhere
breathtaking, when you just take a bite of something seriously mouthwatering or hear an eargasmic song.
Basically when something is really really really good.
