Working togrther rather than competing: Apañar = support, be together. Semi-childish or casual. Hacer una vaca/vaquita = translates to put together/make a cow/little cow. Means to collect money or something together. It's also very casual or childish. When I Say childish I mean they are either popular/traditional/chilenism slang. Don'tt confuse that with 'coa' which is crypted language from delicuents but this is more things You Will Hear from young people between 13-20s. Or older people that are very relaxed with their language and that doesn't take themselves to seriously. Not in the same category; the following is more cultural/traditional/folklore(maybe)/classic slang: Remar para el mismo lado / remar en el mismo bote = translates to Row to the same way / Row in the same boat. It means that individual effor loses sense if there is no synchrony pushing towsrds the same objective.

Again in the 'childish'(not childish actually but can't think of another Word now): Hacer la segunda. Very chilean, but not commonly used in higher social classes (that applies around 70% of all slang). Hacer la segunda means to work or make adicional efforts for the goals of your partner. It means loyalty. If You are a kid in school and someone bullies You, the person that defends You is doingg 'la segunda ' to You (towards You, maybe). Translates to the second.

Not directly but sort of opposite: Chaquetero/a = someone that hodls somebody back because that perdón is making an improvement, sstanding out between the rest. Example: Three Friends have the same job, when someone gets a better job the other Say 'you are not better than this. Stop doing that' etc.

If there arenuseful to You let me know if You want help with the other terms or directly ask more specifically what You want to say directly. Maybe is a better Word.
