What is the meaning of I'd expect nothing less?

Well, when certain races, one in particular, is lazy, can't keep a job, lives multiple people to a one bedroom apartment, cries about "the man bringing them down", you can use this phrase freely.

I think it would depend on the use. I often encounter this phrase when I'm watching anime's, usually when the protagonist gets into a battle with the foe, and then the foe will say "I'd expect nothing less of you" or "I expected nothing less from the leader of the clan". Meaning, the enemy has admitted that the protagonist is strong and he should have not underestimated him.

Hope this will help :)
