It's an exclamation - "What a bunch!" refering to people.

It's kind of the equivalent to "what a bunch of...." ie."¡Vaya panda de idiotas!" - What a bunch of idiots.
Could you be more specific as to the context?

[sosia]

Agree, what a bunch!

Muy común decir en Chile, "Vaya con esta gente", cuando son problemáticos o raros, etc...
