Have a good day 

seriously are you fucking joking right now? you really search for "have a good day"??
if your enemy say this to you, they probably hope you die in a car crash.
synonym: have a good one, have a good night..etc,..

Have a good day. 

At the end of the argument you write
Have a good day.

It means fuck you.

(From a Midwestern / Michigan girl)

You screwed me over, but I want this conversation to end and get the last word in. Have a great day.

(A long argument) - I will take care of it. Have a good day.
