Macockma
A random body part that looks like it was stolen from a monster and glued on in a hurry. It could be your ear, your knee, or even your chin.
My ear is a macockma. It’s been listening to your nonsense for too long.
Your knee is a macockma. It’s been giving you trouble since you were a kid.
My chin is a macockma. It’s been sitting there like it owns the place.
