Mspec

Mspec or m-spec is short for "multi-attracted spectrum", "multiple-attraction spectrum", or "multisexual/multiromantic spectrum".

Plurisexual and pluralian are some synonyms for mspec. A similar term created in 2013 by Julia Serano is BMNOPPQ.

Some people and organizations use the terms "bi umbrella", "bisexual umbrella", "bi+", or "bisexual+" but these terms are sometimes criticized for erasing mspec identities other than bi.
