in the song "Hermit the Frog."
"Well my heart just burst like a glass balloon"
"I was the wrong damn girl in the wrong damn room, I broke my glass balloon."
The feeling of extreme happiness or euphoria, as said by Lana del Rey in the song "Body Electric."
"We get down every Friday night, dancing and grinding in the pale moonlight...I sing the body electric"
