Another word for wonderful. Used to describe a person who is amazing, gorgeous, funny, smart, awesome, sexy and talented. Someone who you are just absolutely amazed by.
My girlfriend is sweet, gorgeous, just plain Gwenderful!
This new girl I met at the club was just so... Gwenderful!
A combination of great and wonderful. When a situation is so great that great or wonderful can't describe it. Saying "this is fucking great" wouldn't cover it either.
O my God, i haven't eaten all day, this quadruple cheeseburger with fries is gronderful.
