This one is easy... Someone puts up a word, and you post the first time you use it in a manuscript. For this game, simple words are better - and it's a good one for posting more than just a sentence. Maybe a paragraph or two.
Let's start... How about "Drove" (or drive, driven, etc.)
From my untitled MS in progress:
Tweeners used shares. Rich fucks drove themselves. Poor folk thumbed it. If you had some pocket change, it was polite to hand it over, but otherwise it was all about each taking care of their own. Poor for poor. Was it dangerous? No more dangerous than driving share or picking one up. Strangers are strangers. No one knew that better than Chase, the motherless child.
