I did not see the word whoopsie in that comic????????
Comics and Editorial Cartoons: Garfield on Yahoo! News
Sorry for the wrong link, and the above is correct one.
It's a word often used when a child falls over - it is an extension of this:
whoops
(also whoops-a-daisy)
• exclamation informal expressing mild dismay
Miss Lillian must have slipped and fallen!
Thanks, Anglika.
So, she just slipped and fell down, and there are no extra implications such as being old, foolish, and couldn't even take care of herself, not to mention being a good babysitter.
Mildly - but Garfield's expression tells you all that too.
in a mild way
Thanks, Anglica.
