you use Facebook to chat with someone instead of calling or texting because you're too lazy to save their number and you're too cheap to buy a phone plan
Hey, I saw your post and thought of you. You're cute. (But I won't call you.)
Why are you still single? You're on Facebook and you're still single. (You're a mess.)
You've liked my post 3 times. What's your deal? (You're annoying.)
