Can a person brake/crack there own collar bone by forcing there arms/shoulders down hard enough?

ok so hear me out when I force my arms/shoulders down hard enough I feel the pressure on my collar bone I was just wondering if its possible to brake/crack my own collar bone by applying enough force in this way.
Update: kelvin you will either need to explain give example or show some medical proof that it's not possible.
Good Luck.
