IAYCFT
Acronym for "In All Your Copious Free Time." Used ruefully to acknowledge that the the the speaker/writer acknowledges that you are already busy, even as the request is being made. Alliteratively, a third party can use the term sympathetically to indicate that s/he understands that you were already too busy when someone added yet another task to your workload.
Hey, I know you’ve got that chapter of the technical report due COB today, plus you’re in client meetings all day, but IAYCFT, can you also migrate the last 6 years of data to a new platform? Great! Thanks!
