GBU is a common internet sign-off meaning "God Bless You" — a warm, friendly way to close a message or comment without getting too formal. You'll spot it in comments sections, Discord servers, and text threads, often tacked on at the end of a supportive or appreciative message. It carries genuine warmth without being heavy-handed about it. In military contexts, GBU also stands for Guided Bomb Unit, a precision munition designation — very different energy from the blessing version.

(military, US) Guided Bomb Unit.
"GBU" means: Guided Bomb Unit.. This is a fairly neutral word with no inherent risk attached. There is no real cause for parental concern; it is descriptive vocabulary rather than something dangerous. If your child uses it, context will usually make the meaning clear. A brief, curious question about where they heard it is generally enough to know whether to follow up.
"GBU" means: Guided Bomb Unit.. Register: neutral, standard English, usable in most everyday contexts. Note the regional or dialect label (US) — usage may sound odd outside that variety. A common non-native mistake is to use the word in the wrong register, or to assume one fixed meaning when it is actually polysemous; always check the surrounding register and the audience before producing it yourself. In formal writing, prefer a neutral synonym or a short descriptive phrase, and use this word only when you have heard or read it being used naturally in a comparable context.
