Nackadactyl
A Nackadactyl is a lying, gossiping nac with wings. It's so annoying it could make a saint swear.
My friend's mom got a Nackadactyl for a pet and now she's mad at her husband.
My brother told me a Nackadactyl was in the cafeteria and now I'm afraid of pizza.
My sister got in trouble because a Nackadactyl told her to draw on the walls.
