Sorry to be the messenger for the bad news, but...
code:
Domain Name: THROWMEAROPE.COM
Creation Date: 02-may-2007
You should've thought of it a year and a half ago.
Anyway, finding domain names is a nightmare, and thinking of one is just the start. In the "big 3" top level domains (.com/.net/.org) almost everything one could want is taken -- most of it by "domain speculators" who register thousands of domains, hoping to hit a handful others will want bad enough to pay large sums of money for. The first to go were the names that could somehow have something to do with anything that might be a marketable product, but by now, one can safely assume that 99.9% of single English language words are taken, as well as any common composites and short phrases.
In your case, it looks like you
can still get throwmearope.net and throwmearope.org. The .org TLD was intended for non-profit organizations of all kinds, while .com was intended for commercial enterprises. These original charters were never enforced and have been almost universally ignored, but if you were to obey them, .org is actually more appropriate for your purpose.
If you like it, you should hurry up and register it now...
