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!!!

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

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!
