A joke like Yo Mama, expect fitted around to mainly suit the English people, meaning Your (correct grammar) and Nan which is commonly used by the Brits/English community. Originated from an Asian (brown) who just randomly said it to someone. Can be used as a substitute for the more meaner 'Yo Mama'. As you can tell from the grammar, this was written by a Brit.
Person 1: Yo Mama's so wrinkly her tits fall to the floor.
Person 2: Duuuudddee
Person 1: Oh right, sorry. Your Nan's so wrinkly her tits fall to the floor.
Person 2: Betterrr

Boy 1: OI! I did your Nan last night!
Boy 2: My Nan's dead...
Boy 1: She wasn't last night!
