They say write what you know, so this is a topic I know all too well. I'm sure many of us can agree on these signs of typical FB behavior.

1. There's a 99.9 percent chance that he is in a fraternity.

2. You can spot him at a daydrink — in a basketball jersey that may or may not be paired with Sperrys.

3. When you guys hang out, he constantly checks his phone.

4. He is a social media whore and may or may not be known as a Twitter troll.

5. Typical bedroom decor includes an American flag, a Sports Illustrated half-naked girl poster, some type of alcohol memorabilia (i.e., empty Jack Daniels handles), and too many personal care items (hair products and Old Spice cans on fleek).

6. Classic Fboy text: "U up?/You going out tonight?"

7. He is conveniently unprepared when it comes to certain precautions.

8. His music playlist consists of everything from The Eagles and Tom Petty, to Kanye West and Katy Perry.

9. Have a date function coming up? You would not even think to ask him — totally unreliable choice.

10. He's a social smoker, typically spotted holding a cigar in one hand and a Keystone in the other.

Yes, these may be some typical red flags of classic FB behavior, but something about their sense of humor and charm draws you in. The dad bod may or may not be an added bonus.
