Concentration Block

A game played by marching bands. It is like the game Simon Says expect it is played with commands such as "Right-Face" or "One set of eight forward" but as the game progresses more complicated commands will be added to elimiate more skilled players. A player is out if he does not follow a command properly. The winner is crowned when s/he is the only one left.

After the band has formed a block they are prepared to play Concentration Block.
Drum Major (to band) : "Right-Face-Move!"
Band executes the move
Drum Major (to student who did not properly move) : "(Insert Name), you're out you turned left."

rock blocking

to block someones enjoyment of music, seeing it, playing it, or hearing it.

I play drums and sometimes do jobs where other drummers will sit in on my kit. One night at a quiet Jazz gig, this jackass sat in and played super loud, repositioned the drums and Beat on them, denting the drum heads badly!! Rock Blocking!!!! I played with a pop band at SXSW at the Apple store in 08. We didn't have a bass played so the Crazy band leader said I shouldn't play because it would be hard for the band even though they had drums set up already, sounded like an excuse not to pay me for the show too!!!! Rock Blocking by your own band mates!!! I have played shows where someone had pissed off the sound guy and he decided to make it impossible to hear ourselves on stage. He also made us sound like shit!! Rock Blocking!!!

clock block

When someone is sitting in class so that they block your view of the clock. You can't check the time without leaning over conspicuously and the teacher noticing

Bryn: Dude that guy was totally clock blocking me, Mr. Richards noticed me looking at the time and kept us for another five minutes.

Oliver: Man I hate clock blockers

cock-block

An action hindering another person's progress. Commonly referenced as a sexually related progress but not exclusively related to just sexual affairs. From the European native art of cock-blocking. "Kalk-block"

My broski really cock-blocked me today by not calling me back in due time. Matt is a real cock-block, he didn't give me a phone number to a potential customer in time! Richards can be a real cock-block at times, he never includes me in his important stories! My brosef was not answering my text messages--he was acting like a real cock-blocking son of a bitch!
