weddingitis

weddingitis
 n.— «It too often occurs that the intimate players involved in a wedding become afflicted with what I call “weddingitis.” The disease is not fatal, but it can kill relationships. It’s a disease in which the stricken individual acts in ways most demanding, most erratic, most wicked, most out of character.» —“‘Weddingitis’ season is descending” by Earline McMichael Kalamazoo Gazette (Mich.) Mar. 29, 2006.
