I would also understand what is meant by these terms if used in a rugby game:
Umpire
Double Movement
Touchdown
Fair catch
Let him up
Punt
Linesman
etc
etc
That is no reason to use them. Rather than pedantry, lets call it "correct use of terminology".
Touchdown. We actually do have that term in the LotG, but its two words, not one, and actually means something else...
[LAWS]Law 22 In-Goal DEFINITIONS
When defending players are first to ground the ball in in-goal, the defending players make a touch down.[/LAWS]
....so its one that should be avoided.
Fair Catch. This actually WAS the correct term for the Mark in 1996. OB will probably know when it changed back to being just mark...
[LAWS]LAW 16. FAIR-CATCH (MARK)
(a) A player makes a fair-catch when in his twenty-two meters area or in his In-goal, he, having at least one foot on the ground, cleanly catches the ball direct from a kick by one of his opponents and, at the same time, he exclaims "Mark!"
(b) A free kick is awarded for a fair-catch.
[/LAWS]
Punt. I don't know why you think this is incorrect.....
[LAWS]Laws of the Game - General Definitions
Punt: The ball is dropped from the hand or hands and kicked before it touches the ground.[/LAWS]
IMO, it is far more important to give the OP (an inexperienced referee asking a legitimate question) some good information and answers to HIS QUESTION, rather than side-track the thread into with nitpicking irrelevancies or getting jobsworth over his use of some colloquial terminology.
The correct "words" are not important to start with, so long as we all understand what he means. The refinements of correct terminology can come later.
