(meteorobs) Earth-grazer definition question

[Thomas Ashcraft]

Definition of an earth-grazing fireball from wiki:
https://en.wikipedia.org/wiki/Earth-grazing_fireball

" An *Earth-grazing fireball* (or *Earth-grazer*)^[2] 
<https://en.wikipedia.org/wiki/Earth-grazing_fireball#cite_note-2> is a 
fireball <https://en.wikipedia.org/wiki/Fireball_%28meteor%29>, a very 
bright meteor <https://en.wikipedia.org/wiki/Meteor> that enters Earth’s 
atmosphere <https://en.wikipedia.org/wiki/Earth%E2%80%99s_atmosphere> 
and leaves again."

Does an earth-grazer have to leave earth's atmosphere to be called an 
earth-grazer?  Can it skim and ablate or burn up entirely and still be 
termed an earth-grazer?

Thanks in advance.

Thomas
