Personal space is a big one. When you're new friends with someone, you're not snuggling, putting your arm around her shoulders, taking naps, etc. If you've been friends for a good long while, that's a different story (depending on you and your friend), but for the most part, you don't sit right next to each other on the couch.
When you hug, you don't do the looooooong, slightly wandering-petting hug if you're just friends. One arm is totally kosher, two arm SQUEEZE is fine, as is the grab and rock back and forth ridiculously - all show fondness, but are not overly intimate.
No expensive gifts. My friends and I will grab a thing of someone's favorite candy because they're down or give them a bottle of nail polish we thought they'd like, but anything bigger, particularly from a guy, is very unsettling. Gifts are also a rare usage item. If you're giving little things all the time and never getting anything in return, it's weird.
You don't lose at games to make her feel better (or him), you don't primp and freak out about what you're going to wear, you're allowed to fart, burping contests usually happen at some point, and you're totally allowed to veto movies when you go out - all perks of not-dating.
