Usually this means code like a[i+2] that should have been either
a[i+1] or a[i+3].

Wikipedia has some slightly different examples 
https://en.wikipedia.org/wiki/Off-by-one_error
but I associate it with the array index calculation being one off.

BTW, such an error happening is actually revealing a code smell. Data
structures and code logic should be written so that it is very difficult
to make such an error.
