A mild expression of joy, gleefulness and/or surprise.
Exmaple one:
Person 1: I wanna eat cake with you
Person 2: Keeks on Toast, really???!
Person 1: Yes, I do.

Example two:
Person 1: What's the difference between chopped beef and pea soup? Everyone can chop beef, but not everyone can pea soup!
Person 2: Keeks on Toast, that's funny!
