Emails like user@cocaine.ninja is fine for random internet shitposting, but if I had to use cockmail for anything involving real life responsibilities I'd go for domains like airmail.cc or firemail.cc at registration.
To be honest, I am tempted to use one of the edgier domain names in my CV just to see their reaction. I'm tired of faking everything's perfect just so the crazies at LinkedIn doesn't send my cv to trash bin.
