The Missing Apostrophe
Any grammar guru will tell you that “Hells Angels” should really have an apostrophe before the first “s.” The club’s name implies that the motorcyclists belong to hell, after all, and so an apostrophe would make that connection clear by creating a possessive. But the organization acknowledges only one proper spelling of its name, and there’s nary a punctuation mark in sight.
The Hells Angels adhere to their own rules – and that appears to include grammatical ones, too. The official website even makes a point to shut down those who question this choice by remarking, “Yes, we know there is an apostrophe missing, but it is you who miss it. We don’t.” And if you want to keep on a member’s good side, we wouldn’t recommend you disagree.
