When you are feeling amazing. Life is pretty good. Must be eating corn on a cob or killing a puzzle. When great isn't quite enough to describe how happy you are you bust out this word.
Only the coolest people on earth use this word. Same thing with beautiful people. When you're blue eyes stop people in the their tracks your that beautiful, your life is grandulous
Mister Cheddah- "Hey beautiful how are you today?"
Ta Ta Rosa- "I am grandulous! Just got 10 pieces in a roll. I am jacked!"
great! grand! wonderful
