John
A John is an excuse for losing, missing a recovery, being hit by an attack, or any number of unfavorable events in Smash. It is a statement or action that detracts from the validity or quality of a competition (or its implied significance), irrespective of truth.
The term John, according to California smasher HugS, comes from a Smash player in Texas (named John) who would consistently invent excuses every time he lost. The term "Johning" became commonplace in the community, as others grew tired of his excuses, thus coining the term.
In Europe, there are some variatons of this phrase:
In Sweden, the term "Yuna" can be used interchangeably with "John", here referring to the Smasher, Yuna, who has the same habit. It's most commonly said completely in Swedish, "Inga Yunas".
In Spain, there are a lot of synonyms to the term "John". It is commonly overheard "No Veyrons" (especially in northern Spain) or "No Joshis" (more common in the south). This is because of Veyron, a Catalonian smasher, and Joshi, an Andalusian smasher; that both have the habit of making up excuses every time they lose.
In Italy, for a certain period of time, the expression "No Dems" was used, referring to Dem-Long, a player from Florence who didn't pass pools in a tournament in June 2006 with the claim that his hands were too cold.
