It only needs two words to describe it (or should that be one word?) -- GOLF!FIC.
From the marvelous kimonkey7's original post:
Pairing: none. gen. Sam and Dean
Rating: R - for swears and blatant implied sexual innuendo of the 12-year-old boy ilk
Need more of a description? Sam and Dean play miniature golf. And nonsense ensues.
(If you're not already familiar with kimonkey7 -- her work is stunning and gorgeous. Beautifully drawn OCs, compelling plots, and the occasional wacky crack. She hasn't written anything for a while, but if you're a lover of angst and massive Dean!whumpage, her library is well worth checking out!)
