What is "spite marriage"

Spite Marriage is a 1929 silent comedy film starring Buster Keaton and Dorothy Sebastian. Keaton and Edward Sedgwick co-directed. It is the second film Keaton made for MGM and his last silent film, although he wanted it to be a full sound film. Keaton later wrote gags for some up-and-coming MGM stars like Red Skelton and lifted many gags from this film in his 1943 film I Dood It, some shot for shot.
