When someone scores a bullshit goal in any games of the popular FIFA series. A slopass goal generally occurs when the ball bounces off multiple players and/or weird angles that conclude in a goal for the slopass player. This leaves the player on the opposing team in a stupor of amazent as they simultaneously delve into anger and throw shit across the room followed by screams and loud cussing.
Many games including those that involve sports have slopass characteristics. FIFA is just an excellent example along with most anything commisioned by EA Sports
