unserious
Lacking in gravity
Unserious describes someone or something lacking gravity, earnestness, or commitment.
An unserious person doesn't take things—or themselves—seriously: He's too unserious to be trusted with the project.
Applied to proposals or arguments, it suggests they don't merit consideration: That's an unserious offer.
The word often carries dismissiveness, implying frivolity where substance is expected.
