Tirar al agua
To throw someone under the bus or put them on the spot, intentionally or by accident. It means revealing a secret or putting someone in an awkward position in front of others. (In Panama, fren is a standard way to say friend, taken from English).
A: Jaime told Lorena that I wasn't with him that night and that he had no idea where I stayed. B: Oh no, friend, that Jaime guy really tiró al agua you without mercy.
