A turkey drawn by placing your hand on the drawing canvas (i.e. chalckboard, paper, wall, etc.) and trace your hand, add a beak, feet, maybe a wing, and that little red flap of skin thing that is customary for turkeys to have.
Come on class, today in kindergarten we will make handturkeys!
the process in which when you are four finger-fingering a girl and you take your thumb and rub her clit while making a gobbling sound at the same time.
