Cabbaged check means: A quick assessment of how drunk or wrecked someone is, often called out by mates before deciding whether to get more drinks or call it a night. Used humorously to gauge the group's collective level. There is no real cause for parental concern; it is descriptive vocabulary rather than risky behaviour. If your teen uses it, context will usually make the intent clear. A short, curious question about where they heard it is usually all that is needed to know whether to follow up.
