do a pocho

When someone is there for you until a better option shows up. Then they leave for that other plan even if they have to let you die.

do a pocho is like

- andres: hey guys take me there, so we can get in the helicopter
- andres: thanks for bringing me... is too late for you guys, im getting in the helipter leaving you all behind, (gets in chopper)
- all of us: -.-
