When you cross the last street coming home and it becomes impossible for cars to bother you anymore.
No more red lights.

When you are waiting to return your rental at a Redbox kiosk and the person in front of you is searching through every movie to find the perfect one.
When I returned my copy of The Dark Knight Rises at the Redbox, I was box-blocked for nearly 15 minutes while some jerk wearing pajama pants finally decided on The Best Exotic Marigold Hotel.

When a dude interups another guy while that guy is speaking to a lady about his line of work by topping his job.
Guy: So I'm an investor on Wall Street.
Lady:Oh, how interesting.
Dude: Well I'm a Chicago city Firefighter.
Lady: Wow, a firefighter! Oh I bet you save lives and everything!
Guy: Yo man. Stop the Job Blocking!
Lady:Oh, how interesting.
Dude: Well I'm a Chicago city Firefighter.

The action of unblocking someone and blocking them again on AIM in order to see if they're online. This is about the equivalent of knocking on someone's door to see if they're home, then your nerves collapse and you run the fuck away before they see you. Usually occurs after a terrible conversation, which ends up with one person blocking the other. Of course, this just makes the person they blocked attractive, so they make frequent spot checks to see if you're online.
paranoia bacon: i am so freaking awesome

rosesnguns17: just make sure you videotape it :):):)

Like "cock blocking" but instead, it's a friend that, for whatever reason keeps the other two friends of a three friend group from becoming close.
*3 friends get into fight, 2 have been hanging out*
Best friend #1: "Why didn't we become bestfriends before now?"
Best friend #2: "I think (insert friends name) has been buddy blocking us!!"
Friend: "Oopsie." 😳

When someone is in the act of rolling a blunt/joint and is about to lick it finished, but is then interrupted by a person causing them to hide "it" thus being Blunt Blocked....
Guy 1: I was in my room rolling a "J" and I was almost done until my bro just walks in, I had to hide it...
Guy 2: Hahah dam dude you were totally Blunt Blocked!
Guy 2: Hahah dam dude you were totally Blunt Blocked!
