Angels Only
Once you've been inducted into the organization, don't even think about joining another gang. "Never combine your support to Hells Angels with other clubs, street gangs, or others if you are unaware of the relationship between those others and the Hells Angels Motorcycle Club," the website reads.
No Apostrophes
You may have noticed that there is no apostrophe in the name of the organization, but that's very much intentional. "Missing apostrophe in Hells Angels?" the site reads. "Yes, we know that there is an apostrophe missing but it is you who miss [sic] it. We don't."
