To behave correctly and not overstep. 'Quedate en el molde' is the Argentine warning to someone pushing too far. It implies you need to know your place and act accordingly.

To reach the same level as the others, especially in terms of alcohol consumption. Also means to get up to speed on something. At an Argentine pre-party it means catching up with everyone who started earlier.

To be on a lucky streak, in a celebratory moment, or with everything going your way. When someone is 'de parabienes' everything is clicking and they have real reasons to celebrate.

A person who uses cleverness to gain an advantage in any situation. The avivado doesn't follow rules — they bend them. Can be admired or criticized depending entirely on context and who got played.
