Your "Bestest Friendest" is someone so close, the title "best friend" just isn't enough. However, you can have a best friend *and* and bestest friendest at the same time-- the bestest friendest would be closest of course, and the best friend would be your second closest friend.
Non-Threatening Gay Friend is akin to a Gay Buddy, sometimes shortened to NTGF. A girl has no qualms about being around a Non-Threatening Gay Friend; he is, after all, non-threatening.
"Man, Jack's been hanging with Emily all night! Is he coming onto her?"
"No, he's just her Non-Threatening Gay Friend. They're discussing prom dresses."
An Xbox best friend is someone that you may have met over Xbox. Their everything that makes you want to get on xbox everyday. Their just like your best friends in real friends, just online. They changed you in a way. You can't live without them and they can't live without you. You always play together and always have a good time. You have the same games and love playing together when they can. Your always excited when they are online. You can't be separated ever. They love you and you love them a lot. You can't picture life without them. Your glad that you met them and never want to lose each other.
I can't wait to get home from school and talk to all my Xbox best friends. I love them so much!
