This word is strictly a reference to beer pong. When you are playing a typical 10 cup beer pong game, wherever it may be, you have the option to "re-rack". Depending on the house rules, this could be either 1 or 2 times in the game. When there are 4 cups left on the table and you want to re-rack them, you have the options of demanding your opponent make you a "Straight
diamond" or a "Nigger
diamond".
A straight
diamond is what
people typically use, which is two cups horizontal and then a cup directly in front and behind. However, you have the option of demanding a "Nigger
diamond" from your opponent (sometimes known as a sideways
diamond). This is when the 4 cups are arranged in a specific manner, similar to the straight
diamond format, but also different. In this case, you set up 2 cups horizontal from each other, one cup in front of these two, but then the last cup you slide around and put it to the right and behind of the front cup. This format is basically just a diamond turned 30-35 degrees to the right so it is in a sideways form.
This word started at a high
school party in farmington, CT and it is spreading throughout the state and soon throughout the country as an official beer pong term. It is clearly the most effective re-rack option when there are four cups left on the table.
"damn dude, we would have been fucked for that
bp game if we didn't remember to call a nigger diamond! That setup cleared the path for our success for the rest of the game!"
