jabbawannabe
Someone who tries to be a jabbawokee but ends up looking like a fool.
My brother tried to do a jabbawokee move and tripped. Classic jabbawannabe.
That girl tried to sing like a jabbawokee but just cried. Total jabbawannabe.
My neighbor tried to dance like a jabbawokee but just stood there. Big jabbawannabe.
