In racing (running/biking), psychological drafting occurs when you spot a person ahead of you with a number in your age group, and you follow that person closely so you can pass him/her when the finish line is in sight.
I was running a marathon and spotted a guy in my age group just ahead of me, so I did some psychological drafting and dusted him at the finish line before he knew what happened.
