When a girl falls asleep on the couch, and refuses to go to bed, with the sole purpose of preventing you from stretching out and relaxing.
Sara was obviously tired, but she refused to leave the couch and hold her position as a blocker.

In online multiplayer gameplay, usally FPS (first person shooter), a 'blocker' is someone who blocks the only exit from a room or other confined space by standing, crouching or lying in the doorway in a way that prevents teammates players getting around them. Usually will gain a fast 'MOVE N00B BLOCKER!1!111' from other players, especially if their escape route from fire or grenades is blocked.
This idiot n00b blocker is trapping me in this room!

Fat, fatter than a normal person. Usually found near a vending machine. Also know as a Walrus or Back Ally Walrus. Known to smell of a combination of bacon cheeseburgers and combos pretzel crackers. Normally seen without a mate due to horrendous nature. Should be captured and euthanized immediately if witnessed. Normally seen with multiple chins and doing walrus shuffle.
Use of term: Blocker, you're a fat fuck. Put the large pizza down and do some fucking work.

A female who looks attractive when she is viewed a block away, but, when she is viewed again closely, does not.
So the other day, I thought I saw my true love when I saw this hot chick crossing the street, but when she passed me by, she was only a blocker.

Courtney Love is a blocker.
