Bestfriendmanship 

Bestfriendmanship (Noun): Someone who is clearly the counterpart of your awesomeness. Often Mall Sessions take place between you and this person.

Me and my Bestfriendmanship Luke, were at the mall, and we gave tons of hugs to random girls because we are extra attractive due to the awesomeness of eachother.

Bestfriendmanshipness 

A word created by a trio consisting of a Mostly-Homo Bisexual Filmmaker, a Bisexual Big-Haired Jew, and a Midget Lesbian with a Lip Ring. It was a portmanteau word created by the Filmmaker in a friendship appreciation card to his best friends. It is an amalgamation of the following words:

Best
Friendship
The suffix -Ness
Man.

It began as "Bestfriendshipness" but evolved to include the MAN after FRIEND because the creator thought it sounded like "Penmanship" which just made the word flow.....

Jenna: "Kaite, you and Doug are my best friends, thank you for showing me unconditional Bestfriendmanshipness."
Kaite: "No problem, I love you best friend! We should bake Bestfriendmanshipness brownies!"
Doug: "Kaite will put weed in the brownies, I vote we just nominate November 10th as Bestfriendmanshipness Day where we all show each other what we mean to one another by participating in a Downtown Orgy."
