When you trip them causing them to fall and is considered a foul
I am a soccer referee and I have never heard that term before, I would imagine it is the sideline.
There is no such thing as disqualifying a foul in soccer. However, the referee may choose not to call a foul because it is trifling, because the referee is not certain that a foul was committed, or because the team offended by the infraction would gain an advantage by allowing play to continue.
i think it would be considered a foul
It depends where and what kind of foul. Also what level
Dissent is not a foul, it is misconduct, and the consequence is a caution.
A foul cannot occur if the ball is not in play. Misconduct can and would result in a caution or a send off.
The restart after a foul will be a direct free kick. Indirect free kick offenses are not considered fouls. A foul must be done by a player, against an opponent, on the field, and during active play.
A foul ball is considered a strike in softball if you catch it its an out. but if it bounces of a fence an you catch it its not an out. If it bounces of an that would have been the third stike then its an out
One example of a soccer foul is tripping or attempting to trip an opponent in a manner that is careless, reckless, or using excessive force.
