bein

Bein means: Wealthy; well-to-do.. It is a dialectal or regional word and rarely appears in mainstream teen culture; usage usually points to a family, regional, or literary source rather than peer slang. 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.

bein means: Wealthy; well-to-do.. Register: regional or dialectal, informal. Not common in mainstream English; use only if you specifically want a regional or literary effect, otherwise the standard equivalent is safer. A common learner mistake is using the word in a register it does not fit, or assuming a single global meaning; native speakers immediately notice when slang appears in formal contexts, so always check the surrounding register before producing it yourself.
