Why rename it from the exact verb for the action I want to do, into a figurative lingo? The functionality sounds ok (giving you the ability to undo a delete) but the terminology on the button just obfuscates it. You're looking for Delete, the button should probably just continue to say "Delete". From a usability perspective, strive for consistency, it is disadvantageous to change words in the interface that users are already familiar with, and which novice users have already been instructed.
