It would probably be broken down closer to how the king cobra is named (their genus name is Ophiophagus which literally means snake eater). Since humans typically have the scientific name Homo sapiens and Human chocolate eater is still human you would still be in the genus Homo. The species name would be broken down into chocolate (scelerisque) and eater (phagi/phagus). Many latin/greek roots are shortened or have their endings changed in the scientific naming process to help categorize species. It would end up being something like Homo scelerphagus, which would literally translate to human chocolate eater or human eater of chocolate.

P.S.: google translate is usually way off on Latin translations, and scientific names generally incorporate Greek/Roman words (which is where phagus comes from) and sometimes other languages as well.

As a genus and species,

you're Homo sapiens with the rest of us.

You have to show a markedly different anatomical, behavioral, or genetic trait, before you, as a holotype are identified and named.

Doubt if behavior alone will clinch it for you.

for example the African spurred tortoise is called Geochelone sulcata (meaning furrowing earth turtle.) Geo-earth chelone-turtle sulcata-furrowing. So I want to be classified as Human chocolate eater. So I looked online and well human is hominis chocolate-scelerisque and eater-edestas, but what order do I put it in? is it as is, so it would be hominisscelerisque edestas?
