1. Sealed shut with tape. You've got to make sure your package is totally taped up before you ship it in the mail. The envelope was taped up so no one would be able to open it unnoticed.
2. Mended or held together by tape. The saxophone I bought at the garage sale is in great condition, though its case is all worn and taped up. The book's pages are falling out and its spine is taped up, but I just can't bear to replace it.
3. Completely finalized or definitively resolved. We're hoping to have this deal taped up by the end of the week. The whole thing's taped up—there's nothing more I can do.
mod. finalized; sealed (up); cinched. (As if one were taping a package.) I’ll have this deal taped by Thursday. Then we can take it easy.
