What is a bogey?
Every hole has a par: the number of strokes a skilled player is expected to need. If you need one stroke more, you record a bogey. On a par 3 that is 4 strokes, on a par 4 it is 5 strokes and on a par 5 it is 6 strokes.
More strokes over par
If you need two strokes over par, that is called a double bogey. Three strokes over par is a triple bogey.

Origin
The term comes from Great Britain and dates from the late nineteenth century. Originally bogey meant the score a good player was expected to make on a hole, which we now call par. Later the meaning shifted to one stroke over par.
