Jennifer was the most popular girl's name from 1970 all the way to 1984, and its sheer ubiquity makes Jennifer seem wholesome, trustworthy — and a little run-of-the-mill.
It's actually all the way down to #84 in America now, but when I was growing up in the eighties and nineties, Jennifer was everywhere. One commenter on The Baby Name Wizard says, "When you are a 'Jennifer' you will always be known by your first and last name, never just 'Jennifer'" — and indeed, I knew a lot of girls who were doomed to go through school as Jennifer L., Jennifer K., or Jennifer W. Perhaps it's inevitable that a name so common would pick up a girl-next-door vibe, and to me Jennifer immediately conjures up the image of a neat ponytail and a nonthreatening expression. Jennifer's pretty, but she isn't beautiful — and she certainly isn't slutty. She's nice, and she has good friends — she might be the kind of girl with two really close besties, but they're no mean-girl triumvirate. Jennifer will lend you an extra pencil if you need one, but she won't give you her kidney. She's not a Beth, after all. The best thing about being a Jennifer is that no one has anything bad to say about you. The worst thing is that they might get you mixed up with all the other girls who have your name.
