A Silkworm
A silkworm is a girl who slithers into your life and leaves a sour taste in your mouth, like bad pizza.
My ex is a silkworm. She broke my heart and left me with a pizza stain on my shirt.
That girl in class is a silkworm. She talks to everyone and leaves me with cramps.
My neighbor is a silkworm. She came over with a pizza and left me with a broken heart.
