stock blocking 

This happens when another customer or a store employee leaves their cart in front of the product, or "stock" shelf that you need something from. Some grocery stores "stock block" themselves by setting up a temporary display in front of other items.

It sucks when you're in a rush to get some things from the store on your way home from work, and the aisles are full of people and their giant shopping carts, packed high and full, stock blocking the few things you came to pick up!

Sock-blocking 

The act of preventing another fantasy baseball team from moving up in the standings by consistently outplaying them. Makes more sense if your team name directly refers to socks, such as the Red Sox or the White Sox.

Fantasy Owner #1: Dude, I've been trying to take 1st place for weeks now, but the Seattle Tube Sox keep sock-blocking me.
Fantasy Owner #2: I know what you mean, man. I haven't been able to overtake the Buffalo Business Sox all season.

Spock-blocking 

When your friend- who looks strikingly like Spock from Star Trek- engages in behavior similar to cock-blocking. Often in brutally failed attempts to hook up with your girlfriend, or prevent you from doing so.

John: Dude, did you get any action last night?

Mike: No, Andrew was fuckin spock-blocking me again.

John: Lame.
