Aggro means: Aggressive intent or behavior; in MMOs/RPGs, the attention enemies pay to a player . Outside gaming: hostile, confrontational.. It is gaming vocabulary; common on Twitch streams, Discord servers, and in lobby chat across most modern multiplayer titles. 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.

Suitable only for casual conversation, chat and social media. Do not use in business, academic or news writing.

For specific readers
Why is this section here?
Slang is read by different audiences for very different reasons. The For parents view re-explains the term in plain, non-judgemental language so a caregiver can understand what their child means without needing the surrounding subculture. The For English learners view focuses on register (when it's safe to use), formal alternatives, and common mistakes — what a textbook won't teach you.
