What is scrum?

Question

what is scrum

Answer 1

ok a scrum involves 2 props, 1 hooker, secondline men, and the 8 man. (how it looks) the props are binded to the hooker who is in the middle, then the secondline men kneel and put there hands in between the legs of a prop, and the 8 man shoves his head between the theighs of the 2nd line men. (how it works) then the reffree says touch and the props quickly touch the opposition prop and then the reffree says hold and engage and then the props on both teams engage there heads togeather and the secondline men and 8 men help push against the other team and the hooker trys to hook the ball back.
