Absolutely anything you want it to be.
Regional variants include "Snapey" and "Snapey Cormack".
Some say that Snape predates time and space.
Although many have speculated that Snapey is the original Snape, he and Baby Snapey are in fact twins, lending a whole new layer of complexity to intersnape relations.
Some say that all of Snapeism grew from a single snape. The rapid rise and proliferation of Snapeism can be attributed to the incredible speed with which snapes rise to prominence in their local communities. From these positions of authority, snapes preach of Snapeism, and the inevitability of complete snape domination. This phenomenon has been dubbed by leading sociologists as Snapevolution. Snapevolution is thought of in certain circles as humanity's final step towards divinity, and as such is a process to be welcomed and aided whenever possible.
As the author of this piece, I simply offer a heartfelt welcome to the ranks of Snapeism. But for those heretics that wish to remain uninitiated, I have but a single warning:
So I snaped him good.
I like snapecakes.
Oversnaping is unsnapessary.
Seagulls snaping backwards.
