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!
