Harry means: The drug heroin.. It is informal slang, fine in casual speech but not suited to formal contexts. It has drug-related associations; worth a calm conversation about which side of the topic your teen is on. 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.

For ESL learners
Harry means: The drug heroin.. Register: very informal, often derogatory or vulgar. Avoid in formal, business, academic, or polite writing. Even in casual speech the word can offend and is best left out of a learner's active vocabulary. 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.

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.

A street name for heroin, Big H is the kind of coded language that emerged to discuss the drug without saying its name outright — useful in conversations where you don't want to be overheard or flagged. The 'Big' prefix suggests both the outsized impact of the drug and a kind of grim respect for its power. Like many drug euphemisms, it's been around long enough to appear in crime fiction, music, and harm-reduction discussions.
