Why a "donut" and not just a donut? Is it a fake?

in my mind. donuts are ring like things with a hole in the
center.
this one is rikes a round bun with cream inside.
and uh, i dunno how to describe it well.. cos my mind went a
little crooked....
but when u bit into it, the cream kind of spurt out.
which means its really filled with cream. of course. uh.
