Pulling a Brian occurs when a male seems very interested in a girl, pursues her for a decent amount of time then randomly decides that the girl is no longer worth it. The male then leaves with the excuses of "I am not ready" or "I haven't gotten over my past girlfriend." It usually occurs a month into dating.
No I am done with him, he started pulling a Brian.
