twainiac

A former student of the mark twain school, which featured grades 7 through 12 and offered kids who were coded as emotionally disturbed (nutty) a place to run amok with other such unbalanced and often dangerous fools. The school is located in rockville Maryland next to a large forest area. Staff members often restrained students physically then went home and masturbated to the memory of it. Mark Twain would be the last place you might want you're child to end up unless you were grooming them for a circus side show act.

That child just beat up that other child with a trash can, i think they might send him to Mark twain, what a twainiac he will be indeed!

Shania Twaining

After being cheated on by your spouse with your best friend, getting them back by hooking up with your best friend’s spouse.

This term comes from the factual scenario when Shania Twain’s husband cheated on her with her best friend. Shania Twain later divorced him, and married her best friend’s husband. This really happened, I shit you not.

Jim: “Wow, I can’t believe our best friends are idiots and decided to cheat on their spouses with each other.”

Rachel: “Yea, but that’s ok, the real winners are Mike and Sarah. They ended up Shania Twaining in the end.”
