The use of words in writing or saying that is the opposite of what is really meant is known as verbal irony.
Explanation:
Verbal irony is when someone says or writes something but she meant just the opposite of what is really written or said, meaning the opposite of the literal word. It is employed by many writers in their literary works.
Examples may be like when someone has a bad day but then says "her day is definitely going great"
or when the place is messy or congested but then people say "you deserve an award for cleanliness"
or claiming the weather is perfect when in reality it is really raining cats and dogs.
