Bakait means: A boastful, overconfident, or rowdy person who talks or acts with exaggerated bravery, often without substance; a showoff or know-it-all.. It is mainly Indian English and may not be understood outside that context. 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.
