Has little or nothing to do with anticipated results. It's not limited to sports or competition. You can choke on an assignment for work, choke in an attempt to seduce a crush of yours. Jordan missing a free throw. You can choke anywhere, anytime.
Choking is when you had control, and failed to execute.
What happens is you are suppose to be focused on what your eyes are viewing. But your weak mind chooses to worry about something negative whether real or not, past or future.
It's bigger than that
Michael Jordan would be considered one of the most clutch professional sports players of all time.
Only you know when you choke. Its a distinct feeling. Choking doesn't give a crap about expectations.
