For parents

"caffeinate" means to drink caffeinated beverages in order to increase one's energy or wakefulness or to enhance physical or mental performance. It is one of many casual words teens pick up from friends, social media, music or sport, and on its own it carries no particular warning. If you hear your teen use it, it is fair to ask what they mean by it in their friend group, since meanings drift quickly. Asking out of curiosity rather than alarm tends to keep the conversation open and useful.

For ESL learners

"caffeinate" is informal English meaning to drink caffeinated beverages in order to increase one's energy or wakefulness or to enhance physical or mental performance. It is used widely across English varieties. A more formal or neutral equivalent would be something like "to drink caffeinated beverages in order to increase one's energy or wakefulness or to enhance physical or mental performance" expressed in standard vocabulary. A common mistake is to assume "caffeinate" can replace its standard equivalent in every register; keep it for spoken or casual situations and use the formal form in writing.
