What does "おはろー( ´Д｀)ﾉ" mean? Japanese help?

[Riada]

It's a tweet, from twitter of course. Just wondering what it means in English. I know there's a smiley there, but can't make sense of the "Oharo" or "Owaro" /etc... any help, please?

[玉菜畑]

It's slang for good morning.

[wind-sky-wind]

It's the mix of "おはよう" and "ハロー（はろー）."
"おはよう" is "Good morning," and "ハロー" is the loanword for "hello."

"よう" yo rhymes with "ろー" ro.
What an interesting invention!
This, however, is used by the limited few young.
