Niall 

1) The spelling of the "Nile River" by a person with bad spelling skills, or by a "Directioner".
2) The name of a boy when the parents like the Nile river and think it looks cute spelled with an "A", two "L"s and without an "E".

I failed my geography test, I was in One Direction land and spelled the Nile River "the Niall River".

Let's name the baby Nile. No, make it Niall because that sounds less Egyption.
