no laughing matter

Not at all funny

Something serious that shouldn't be treated lightly or joked about.

The phrase typically pushes back against dismissiveness: Food allergies are no laughing matter.

It can sound slightly old-fashioned or emphatic, often used when someone fears their concern isn't being taken seriously enough.
