Mother-May-I-Super-Sunday-Sandwich-Eternus-Dibs

How you claim something eternally using dibs. If you say or write it wrong, someone can get the chance to eternally claim it before you correct yourself. Nothing beats this, and whatever you eternally claim is your's. Unless your friend is a sore loser.

"Hey, I want that!"
"Mother-May-I-Super-Sunday-Sandwich-Eternus-Dibs!"
"Damn it."
