A great wedding gift idea for your friend who loves poetry slams could be a book of love poems. There are many fantastic collections of love poems that you could consider, such as "Love Poems" by Pablo Neruda or "The Essential Rumi" by Rumi. Alternatively, you could look for a book that focuses on the theme of weddings, like "The Wedding Poem" by Linda D. Hill or "Wedding Day Poems" by Max Ehrmann. Additionally, you could consider getting them tickets to a poetry slam event, or even hiring a local poet to write them a custom poem to commemorate their special day.
Or you can get her/him a star map with the date of the wedding.
