Cherokee Grandmother Syndrome 

Claiming one has some distant Native American ancestor in order to sound more exotic or interesting when in fact no such Native American ancestor exists.

This practice is also relatively common by some American celebrities and personalities.

Larry: "And my great-great grandmother was part Choctaw and Apache."

Bob: "Larry, that's BS, your paternal grandparents where German immigrants and your maternal grandparents were Irish immigrants. You sound like you have a case of Cherokee Grandmother Syndrome."

James: "Hey did you hear Elizabeth Warren is 1/32nd Cherokee?"

Dustin: "Pff, yeah sure man"

Hubert's Grandmother

The sexiest human being ever. Quite attractive but kind of takes things too fast. She usually tells Hubert that 'somebody at du phone 4 u'. She has a relationship with Hubert's friends Tin Nooyin. She is extremely hot and is kind of a slag. She usually spends days out and sleeps elsewhere. She is rude but honest. And She hates Ichibon Sushi.

Person 1: Hubert told me his grandmother gave him some special favours when she saw his good grades.
Person 2: Dang, Hubert's Grandmother is hot.
