Post-Sesh Intensification 

the ramp-up in highness following a cannabis-based smoke session, usually rising by 1 or 2 extra points after the initial peak is reached

After smoking with my friends, I went home to watch TV. It was after sitting for a couple minutes that I got PSI (Post-Sesh Intensification) and went from a 6 to an 8 almost immediately.

Post Wait 

The act of deliberately waiting to write a post or comment, so that you can avoid commenting on it immediately after it was written. This act makes it look like you're busier than you really are, instead of revealing the fact that you are on facebook constantly.

Can also be used for texts, emails, chats etc.

Friend #1: DUDE check this out!! This is totally cool! (link)
...wait...
...wait...
Friend #1: hello? are you there?
Friend #2: oh hey, yeah that's awesome, sorry I was busy working.
Friend #1:no you weren't working, you were pulling a Post Wait on me!

Post Infidel 

The act of posting a response to the wrong status on Facebook. This person on your feed is so used to you responding to every status that you might as well be married. This person is now worried about you giving a response which has absolutely nothing to do with the status, and therefore knows you've been stepping out on him/her with another status.

Sheryl: What was up with your status about apples and then Theresa started talking about tampons?

Prudence: I know. I suspected she was a Post Infidel, but had to catch her in the act.
