You wouldn't happen to know Tarri would you?

Tarri and I are intimate lovers with one-hundred thousand kiddies, and we live a primal, raw, passionately lustful existence in a small outhouse in the outback while dropbears scream into the aether and kangaroos play the didgeridoos.
We met in a bar one fateful night and got totally wasted. Next thing we knew, baby number 12 was on the way because we were just that drunk, and now we are hiding from the law and living off iguanas and crocs.

Nah mate just kidding.
Are you referring to a christian name or username?

The Artist I I'm referring to.

That is the general assumption, but the question was if Tarri was their first name, or username.
I have personally never met someone with the name or username Tarri in real life or online, but the question was in case you used a real name when the username is different.

Their Username is Tarri she's a somewhat popular artist in the community.

I guess I shall have to take your word for it!
But admittedly no, I don't know any girl called Tarri.

Me I’m the clerk out of the shot of the picture internally screaming “MAKE UP YOUR MIND, YOU’VE BEEN STANDING STARING AT THESE CEREALS FOR TEN MINUTES!”

Infliction of internal destruction in others complete.
Mission accomplished.
