Lagoa
A lagoa is a person who thinks they’re cool, but they’re just a loud mouth who can’t keep their trap shut. They’ll eat your secrets for breakfast and then tell them to your ex for lunch.
'You’re my best friend!' Then they told my ex I had a crush on them.
'Don’t worry, I won’t tell anyone!' Then they told my crush I had a crush on them.
They said they’d keep my secrets... and then they told my crush I had a crush on them.
