This came up on the Wizard's forum: Do you spell the plural of Yo with or without an apostrophe?
Yo is an expression used for the number "eleven" in the game of craps. Yo is used so that there is no misunderstanding when a player calls for a bet on eleven because a dealer might think the player said "seven." A player calling out "give me a five dollar yo" is more clear than a player calling out "give me a five dollar eleven."
I have always wrestled with whether or not to put an apostrophe into the word for the plural of yo.
We have craps for "any craps" but there is the singular "crap" bet as in "any crap." We can also say "any craps." No apostrophe is used.
But without an apostrophe the plural of "yo" is "yos" and that might be a problem.
I checked various dictionaries for "Yos."
"Yos" is most often listed as a derogatory word. (While "crap" or "craps" might be an offensive word, it is not a derogatory word.)
"Yo's" also appears as a contraction of similar derogatory words.
Some players who don't want to utter the word "seven" at the table will call that number "the devil" or "big red," or might even go to the extreme and say "the number between six and eight."
Perhaps instead of saying "Yo's" or "Yos" which can be derogatory words, we should simply say "elevens" which is not derogatory and only can be mistaken in speech and not in text?
