tablocking 

videotaping any performance using your tablet held above your head thus blocking the view of everyone behind you.

I couldn't see my kids performance because the lady in front of me was tablocking.

Titblocking 

When lesbian couples get interrupted by someone! similar to cockblocking but more fitting as its two women so hence tits. (titblocking titblocked etc)

Wynonna was titblocking Waverly and Nicole as they were kissing on their bed by opening the door and interrupting them. Waverly yelped in surprise and Nicole eye-rolled as they were close to sexy times ;)

talkblocking 

when you are tring to have a conversation with one of your friends and you dont want anyone else to hear, but instead someone keeps trying to join it and keeps annoying you. similar concept to cockblocking.

i was trying to talk to James bout women while we were walking down the hill, but instead some lousy dude decided talkblocking us was a great idea
