g-note syndrome
You're so obsessed with MCR that you'll break out into a dance or a full-blown tantrum when you hear a g-note.
I was in the bathroom and heard a g-note, and I did a full dance in the mirror.
At the park, I started screaming and doing cartwheels when I heard a g-note.
I broke my phone because I was too upset when I heard a g-note.
