What is the usage/meaning of ご馳走さま (lovey-dovey)?


Edict states that one of the meanings of [ご馳走さま](http://www.edrdg.org/cgi-
bin/wwwjdic/wwwjdic?1MUJ%E3%81%94%E9%A6%B3%E8%B5%B0%E3%81%95%E3%81%BE) is
_"used after hearing something lovey-dovey"_.

Does anyone know some examples whereby ご馳走さま is used this way? Specifically,
how do we use "ご馳走さま" and when is it appropriate/inappropriate to use it?

Also, imagine we have this conversation between two people:

> A: Yesterday I kissed my baby.
>
> B: ご馳走さま

What exactly does B mean when he says ご馳走さま?

What will this "ご馳走さま" be when translated to English?
