Quoting from 1994 means you are not a child here and based on your subject matter, those things are common in the football scene. When I read your out listed actions, I laughed. All gamblers do the number one. A gambler bet against another club and mistakenly, your supportive club player scored his own goal. Lolz.. the player will receive enough insults unless the team win the game and the ticket didn't cut and the gambler win the game.
To some gamblers that is a common loss it is not easy to give up on that.

Unless the gambler bet on 1 goal in the first half by any team then he will not cursed the player and he will be very happy for that because he has won his betting ticket.
