To spoil someone's enjoyment of something, good mood, or plan. A colloquial expression.
Lass dir von dem schlechten Wetter doch nicht den ganzen Ausflug vermiesen!
Don't let the bad weather spoil the whole trip for you!
The verb is made up of the prefix 'ver-' and the adjective 'mies' (bad, nasty). So it literally means to 'make something bad' or to spoil it.

The rain spoiled the trip (accusative) for us (dative).

„Verderben“ and „vermiesen“ can both express that something enjoyable or a plan is no longer good. „Vermiesen“ is colloquial and usually emphasizes the person whose enjoyment is taken away; „verderben“ can place more emphasis on the thing that has been spoiled or on the mood itself. In everyday language, either word is often possible.
