I believe the only actual requirement is that it has to be 3 characters or longer, as two characters are reserved for countries.
Would be kind of cool, most attacked domain on the web, probably
One of those criteria is that you actually do something with the gTLD — per their FAQ:
> ICANN expects all new gTLDs to be operational. One of the reasons ICANN is opening the top-level space is to allow for competition and innovation in the marketplace. The application process requires applicants to provide a detailed plan for the launch and operation of the proposed gTLD. gTLDs are expected to be delegated within one year of signing a registry agreement with ICANN.
A few highlights from the full evaluation criteria (https://newgtlds.icann.org/sites/default/files/evaluation-qu...):
- They will reject applications made by known cybersquatters
- They will reject your TLD string if it has rendering problems on major OSes (e.g. if its codepoints aren't covered by at least fallback fonts)
- They will reject your registration policies if they're incoherent or unenforceable
- They will reject your application on behalf of a community if you can't provide sufficient references establishing that you actually represent the interests of that community
- They will reject your application if you haven't outlined to their satisfaction a plan for continuity/migration of control of the gTLD from your organization to some other organization in case of the bankruptcy/dissolution/etc of your organization (note: this is a separate thing from the technical considerations of registry fail-over et al, which are more something that most applicants would have a technical registry partner fill out on their behalf)

In all, the process actually seems quite thorough — but as with regular domain-name registration, it's a default-accept, not a default-deny, policy. The more arbitrary gTLDs that have been established so far all just-so-happen to be "innocent" of all of the disqualifiers.
Specifically, I think, given the criteria, that any multinational company could probably expect to be able to acquire its own name and trademarks as gTLDs without much fuss; and recognized leaders/stewards of any major religion (or other non-country-endemic sociocultural group) could likely get any jargon term specific to that religion/subculture as a gTLD. Those two cases together cover most of the "weirdness" in approved applications.
One assertion I might make after reviewing the evaluation criteria, is that very few of the criteria look at the gTLD string itself. Almost any gTLD string is a potentially valid registration. Almost all of the evaluation process is set up to establish whether you, the applicant, have a valid claim for stewardship over the given gTLD string.
