Wow for people recommending Guiness, don't you think that's a bit heavy for a noob beer? It's still a decent place to start though, for anyone looking to go down that road. I personally started with really crappy American macro brewed beer, which I think has allowed me to really appreciate all the good beers out there while not being a total snob about it (refusing a Coors Light someone buys me at a bar is a pretty dick move, imho. I'll even still drink PBR or Keystone for beer pong and at parties).
Also, I don't think a lot of people have mentioned that many "chicks" don't drink beer because many mixed drinks contain less calories per how drunk you want to get. It takes a lot of games of beer pong for me to even get tipsy, nevermind drunk, whereas I can have two long islands and be good for a few hours. Also, umbrellas are cool.
Anyway, for noobs, I'd say amaretto sours are a pretty good bet. Low alcohol content, tasty, usually not too pricey to make/get at a bar. I also really like introducing people to Wild Blue, which is a delicious blueberry lager, because it's easy to drink, unique, and not too expensive. I don't know a lot of people that don't like that beer. I personally, prefer whiskey sours or seven and sevens (Seagram's 7 and 7-up).
People are getting pretty riled up about how sexist the term "chick drinks" may or may not be. I know a lot of my friends don't find it offensive, but I can also kind of see the opposing argument. Randomly labeling things as misogynist is a little dangerous though, as misogyny implies an active hatred/contempt of women, and I don't think "chick drinks" really falls into that category. Yes, the term is problematic, but I also think we can be too sensitive. (By the way, a lot of women choose to drink hot pink martinis because it makes them feel more feminine, or because they like the taste, or wanna be more like SJP, or whatever. There are a lot of cultural stereotypes and meanings associated with ALL types of alcohol. We can't just ignore that.)
BUT I really don't think that phrase can/should be replaced with "noob" drinks either, especially offline. Many people choose to drink noob drinks way after they started drinking, and as we can see from this thread, everyone has a different opinion of what a noob drink is.
