Sarcasm

Sarcasm: the last refuge of modest and chaste-souled people when the privacy of their soul is coarsely and intrusively invaded.

– Fyodor Mikhailovich Dostoyevsky

Sarcasm

Sarcasm is sneering, jesting, or mocking a person, a situation or thing. It is often used in a humorous manner and sometimes expressed through particular vocal intonations. Sarcasm is often expressed in ironical statements. It can sometimes be the sincerest form of discourse for the emotionally fragile. This is often done by simply over-emphasizing the actual statement, or particular words of it.
