type 1 fun

Type 1 fun is just plain fun. Simple, uncomplicated fun. It differs from 'fun' because it implies that there was a possibility for type 2 fun or even type 3 fun to have occurred instead.

a: "So, how was your boss's BBQ?"
b: "Oh, everyone got plastered and played twister. Proper type 1 fun."
a: "See, told you it would be fine."
