List: Hypothetical reasons for removing someone as a Facebook friend

Karine and I got a little silly on MSN tonight thinking about reasons that one would remove a friend on Facebook (not to be confused with not accepting someone as a friend in the first place). What if Facebook required a reason before allowing you to unfriend someone? What could they be?

1. "She got drunk and made out with my boyfriend." [You could also use the "event" option to specify at which party this occurred!]
2. "Never returned a movie I rented."
3. "Regifted the CD I got him for Christmas."
4. "Borrowed a book from me and wrote in it. In pen."
5. "When we go out for dinner, she never pays her fair share of the bill."
6. "Refused to set me up with a friend because 'I don't want to be held responsible for the consequences.'"
7. "Latently racist."
8. "Made a pass at my mom."
9. "Watches The Colbert Report unironically."
10. "Lied about living in Iceland."
11. "Prefers MySpace."
12. "I can't remember why I accepted his/her friend request in the first place."
13. "Not interested in 'anything I can get' after all."
14. "EMOTIONAL FUCKWIT."
15. "Got her pregnant."
