Yes, you can say that. "Of" is understood even if you don't say it.
Look up the famous nonsense poem "Jabberwocky" by Lewis Caroll. It contains these beautiful lines:
“Beware the Jabberwock, my son!
The jaws that bite, the claws that catch!
Beware the Jubjub bird, and shun
The frumious Bandersnatch!”
Some of the words are nonsense words so don't expect to find them in a dictionary.
