Indian compliment
When somebody gives a compliment, then says something derogatory about you, they gave you an Indian compliment. A person who gives an Indian compliment is an Indian compliment giver. Like telling somebody they're attractive then telling them they're narcissistic.
Its just as good not to give any compliment at all than to give an Indian compliment. Both ways are about as refreshing as a leaky garden hose with a sprinkler at the end of it on a hot summer day.
