look up any word, like blumpkin:
 
1.
Have a good day.

A pre-emptive strike against the saccharine, sing-song of a "have a good day" from a bored, indifferent sales clerk.

Similar in construction to "goodbye" which is said to be a contraction of "God be with you".
To the cashier at the grocery store upon leaving ... "hagody"
