Polybomb

Also: poly bomb, dropping the polybomb

Disclosing to someone — a date, a partner, a family member — that you're polyamorous, especially when it lands as a sudden, heavy revelation. The term captures both the act and the hope of doing it more gracefully.

A polybomb is the moment of telling someone you're polyamorous when it hits them as a shock — a first date learning it over dinner, a monogamous partner hearing it for the first time, a parent finding out there are two partners, not one. The 'bomb' framing acknowledges that even a calm disclosure can detonate emotionally on the other end, especially for people with no prior frame for non-monogamy.

The community uses the word partly self-critically, as a reminder to disclose thoughtfully rather than dump. Better practice tends to mean telling people earlier rather than later (so it doesn't feel like a long-running secret), framing it matter-of-factly, leading with what's stable and happy, and giving the other person room to react and ask questions instead of demanding instant acceptance. The goal is to be understood, not to win the conversation on the spot.

Done well, the 'bomb' is defused into simply being out — one honest fact about your life among others. Done badly (sprung late, defensively, or as an ultimatum) it tends to produce exactly the explosive reaction the name warns about.

Where this term fits in the wider picture

Ethical non-monogamy is a network of overlapping practices, identities, and structures — and Polybomb connects to several of them. The neighbouring terms below show how this one sits alongside the rest of the vocabulary practitioners actually use; the guide at the end is the longer-form treatment of the same territory.

Closely-related vocabulary

Mononormativity
The cultural and structural assumption that monogamous, dyadic, life-long pair-bonded romantic relationships are the natural and correct form, with other configurations treated as deviations.
Amatonormativity
The widespread assumption that a central, exclusive, romantic-sexual partnership is the universal goal everyone should organise their life around — and that lives without one are lacking.
Polyam
The community-preferred shortening of 'polyamorous' / 'polyamory,' increasingly used in place of 'poly' to avoid colliding with Polynesian people's reclaimed use of 'Poly.'
Boundary
A statement about yourself — what you will or will not do in given circumstances — distinguished from a rule, which is a statement about what another person must do.
Agreement
An explicit, negotiated understanding between partners about how the relationship will operate — distinguished from rules in modern polyamory writing by being mutual rather than imposed.
