Osananajimi 

A commonly-used term in romantic anime, an osananajimi is a friend from infancy, a childhood friend or old playmate with whom one shares the special and intimate understanding that (according to such stories) can only come from having known each other since earliest childhood.

A good example of Osananajimi is Manami Tamura from Ore no imouto

Osawatomie 

A small town in Kansas, USA that is the armpit of the Universe. If you live here you are either poor or dumb, possibly poor AND dumb.

I'd rather be raped with a cactus than live in Osawatomie.

Osama Bin Laden 

The greatest player of hide and seek the world has ever known, rivalled only by Wally/Waldo.

Where, where, where, where's Osama?

Let's play hide and seek, just like Osama Bin Laden does for a living!

Osama Bin Laden 

Kind of like Waldo, only with a turban instead of a striped hat.

"Where's Waldo"? Do I wanna fucking play "Where's Waldo"? No man, I wanna fucking play "Where's Osama Bin Laden".

Now THAT'S a challenge.
