Lagoa Syndrome
Lagoa Syndrome is when someone takes your secrets and turns them into a laughingstock. They're the type to tell your business to everyone just so they can be the center of attention.
'Your secret is safe with me!', she told your crush you had a crush on his ex.
'Don’t worry, I won’t say a word!', she told your mom you were getting a divorce.
'We’re besties!', she told the whole school you were getting married.
