Post-Date Depression 

Usually occurring the day after you go on a date with your girlfriend/boyfriend when you feel extremely sad and lonely because you had such a fun time with that person and now you miss them a ton.

"So how was your hangout with Chloe last night?"

"Aw, man it was amazing, but I've got some serious post-date depression right now. I miss her like crazy. AHHH!"

post bday facebook drought

When an individual does not receive any comments or notifications on their facebook for a period of time after their birthday because everyone figures they've had enough wallposts and attention for awhile and because nobody has anything else to say that is considered relevant.

Friend posts on wall: Hey man how you've been?
Friend responds: Good man, but I know you're just commenting on my wall to get out of that post bday facebook drought you're in because you had a successful birthday wallpost count and no one wants to spoil you with more notifications!
