Bole was a Beater on the Slytherin Quidditch team who deliberately fouled Alicia Spinnet in the 1994 Gryffindor-Slytherin Quidditch final. He hit her with his club, and then claimed he had thought she was a Bludger (PA15).
Then again, given the usual standard of Slytherin Beater brainpower, maybe it was an accident….
A bole is the trunk of a tree, an apt name given the build of a typical Slytherin Beater.
As Bole's last year at Hogwarts was the 1994-95 school year (OP19), he is likely to have been born during 1977.
