Spontabulous
A mix between spontaneous and fabulous. Usually used to explain a random, but equally awesome moment in time. It could be looked at from many angles, and even called fateful that something so spontabulous could have ever happened.
"Whoa, that concert we went to last night as so cool. It was really gnarly when we got to meet the lead singer; that was spontabulous!"
"Yeah, I didn't think they'd let us."
"Yeah, I didn't think they'd let us."
Spontabulous
The point at which something is no longer spontaneous or fabulous, it becomes spontabulous.
I hope you have a spontabulous birthday
