Hey everyone!

So my friend gave me a little challenge he has multiple Instagram accounts and said if I can figure out the username of his secret 3rd account, he'll give me some price

Here's what I know:

i think it has something to do with tiger

the username has 8 letters

the username end with "r"

This is purely a fun little challenge between us not trying to stalk or invade privacy.
If anyone can help me figure it out, I'd be super grateful
