nigga size
This word is used mainly to show a size of something that is so large that it goes past the size of even "Extra Large". This word originally came about when referring to items such as shoes and clothing which are, in a stereotypical manner, considered to be extremely big in size when it comes to black people. It can also be used to refer to anything that is a lot or large in general. In a derogatory manner, it could also refer to the size of someone's dick.
