v.1. To refurbish, improve, or embellish something: The designers vamped up the website using contemporary colors. I bought an old bookshelf and vamped it up with a new coat of paint.
2. To put something together; fabricate or improvise something: With no hard news available about the summit meeting, the reporters vamped up questions based only on rumor. When my turn came to tell a story, I vamped one up from tales I had heard as a child.
