A jabbawannabe is a person who tries to be a jabbawokee but are just plain stupid.
My uncle tried to be a jabbawokee but said 'fluffy banana.' Stupid jabbawannabe.
That kid tried to be a jabbawokee and just drew a cat. Plain stupid.
My neighbor tried to be a jabbawokee and just yelled 'moo.' Total jabbawannabe.
