When a person you want to either be friends with, date, be in a relationship with, or have sex with won't willingly hangout with you in person and limits you to communication through Facebook usually because they don't know you well or don't want to know you well for various reasons. Can sometimes include texting to an extent. Usually will make you feel like a desperate asshole for continuing to try (unless you're self-absorbed). Can sometimes be worse than the friendzone depending on the situation. Is extremely common with people you add and have mutual friends with but haven't met in person.
Clay - "Man, Emily facebook zoned me last night..."
Bob - "Ouch, how exactly?"
Clay - "I just asked if I could take her out and buy her dinner...she said she doesn't hangout with people she doesn't know well"
Bob - "Ooo, yeah, didn't you hear? Girls are allergic to dinner."
When you add/are added by a person of the opposite sex on Facebook, and it leads to you developing a platonic friendship instead of the originally-intended relationship
I added Kristie on Facebook to get to know her and ask her out, but it isn't working out. Now I'm in the Facebook friend zone.
Someone who jumps from one relationship immediately into another one.
Serial monogamists can not stand to be alone and often suffer from vast commitment and insecurity issues.
Because they jump into relationships immediately after the previous one has ended, serial monogamists typically don't take the time to reflect on their behavior or why their previous relationships failed; thus, they end up making the same relationship mistakes over and over again.
Person 1: Damn, Dustin already has a new girlfriend?! It's only been two weeks since he broke up with his fiance! I think he's a sociopath.
