ladonna syndrome
when you laugh like a hyena and randomly start singing like a bad karaoke singer
At the bus stop, my friend saw a pigeon and started laughing and singing ‘I Will Always Love You’ to it.
During my lunch break, I got Ladonna syndrome and sang ‘Don’t Stop Believin’ to my sandwich.
My brother got it during my little sister’s tantrum and started laughing and singing ‘Sweet Caroline’ at the top of his lungs.
