Get the Uncle Bob mug.
A term created by wedding photographers to describe a guest at a wedding with a SLR camera with big lenses and a flash gun.

Uncle Bob has little understanding of his own equipment which is often better than the official photographer and likes to get in the way of the wedding photographer spoiling and directing shots.
There was a total uncle bob at last nights wedding asking me how many megapixels my camera had and he was constantly getting in my way!

Term that snobby “pro photographers” use to whine about anyone else who takes photos at a wedding or other event. These “pro photogs” are often under the impression that relatives of a wedding couple cannot possibly have any sort of enlightened photography experience or talent, and that they are the only ones who have talent. Sour grapes often seem to be at play, with the “pro photoggloating about how they get “better shots” even though the “Uncle Bobs have better gear.”
“That Uncle Bob has superior equipment, but cannot possibly have any talent in photography because no one else on this planet can use a camera besides me”
