A ridiculously bad foosball goal. Most often the perpetrator
of such an offense has no foosball skills, and relies on cheating or "flukes" to score.
The most significant use of the term was in 2002 during a series of legendary foosball games at the University of Northern British Columbia a player, having lost a number of games began to shake the table. In his inglorious method of distracting opponents, he began to score goals, even winning some games.
The entire universtiy foosball population began calling his goals cheesy, although the reason remains unclear, especially seeing as he didn't even go to the damn school. Some refer to the goals as cheesy because they "Stink". Other use the term because the player that scored such a fluke of a goal operated a cheese factory on his parents farm. Still others probably came up with it while blazing a fattie
To this day, poor goals in foosball are known as cheesy, and the term has spread as far as Europe where the French say "Fromage" in the event of poor goal.
