Sarcastically means in a mocking way that means the opposite of the words. Said sarcastically, smiled sarcastically, asked sarcastically.
It cannot be conveyed in writing without help, which is why anything said sarcastically needs a marker and why so many messages are misread. Tone alone carries it in speech, and children learn to hear it surprisingly late.
