Considered to be the "next level" in the progression of the your mom insult meme. Perhaps even more meaningless than your mom, if used in seriousness it indicates the speaker is either drunk, drained of insults, or has truly been scraped from the bottom of the gene pool. If used properly in jest and in conjunction with biznatch and other psuedo-ghetto terms it can lead to hilariously nonsensical conversations.
Speaker 1: You're ugly.
Speaker 2: Your mom is ugly.
Speaker 1: Your mom's face is ugly.

Speaker 1: You should give me that book.
Speaker 2: Your mom should give you that book.
Speaker 1: Your mom's face should give me that book, biznatch.
Speaker 2: Heezy, don't get up in my jive. Your grandmom's face is going to give me that book or I will bust a cap in your grill.
Speaker 1: Your great-grandmom's face is going to bust a cap in your grill.
Etc.
