What's the word Thunderbird?

I hate Thunderbird. It is like a public toilet with no doors. It leaves your INBOX loaded and easily accessible with NO security or privacy.

What's the word? Thunderbird.
A man got hit by a flying turd.
Couldn't swim, couldn't float
so all that shight went down his throat.

The word "thunderbird" is "thunderbird". (The question is vague, so I cannot provide better information)
