A tilly
A Tilly is a lovely girl who gets a little jumpy and has weird cravings. She might eat a whole pizza at 3 a. m. just because she felt like it.
Tilly: I just ate a whole pizza at 3 a. m. I'm a monster.
Tilly: I was jumping out of my skin when I heard that loud noise.
Tilly: I can't stop thinking about ice cream. I'm obsessed.
