A person who sucks so bad at something that the word "noob" isn't enough to compare to what they are. It's just a higher version of a noob.
Rosa is so bad at soccer she isn't even a noob. She's a noobula.
An uber noob, coming from the terms noob (n00b), and nebula (which by the way is VERY large). If you are this, you are a noob (n00b) the size of a nebula. Lose some weight, chubby.
Can be written: n00bula, n00bul4, n00bu14
"You are a noob the size of a noobula!"
