Get the Erinmug. 
A saying that will make no sense and may seem like it will come from someone with little to no knowledge, even though the sayer of the phrase is very intellegent. This can happen anywhere at anytime of day, you just need to pay attention and listen for them. Usually once the phrase is said everyone around that heard it will stop with their jaw dropped and be like "Did you really just say that!?" Alot of laughing occurs after this.
Erin - "Does the cheese have cheese?"
*everyone around": ERINISM!!!!!!!!

Erin - "Do they want ice in it?"
*everyone around": ERINISM!!!!!!!!

A short, blonde haired ,blue eyes girl with a great sense of humor. Usually white but into blacks. Is tough on the outside but sensitive about her height. She can be very inappropriate but never crosses the line too far. She is beautiful and has a great family. They might not always get along but blend well together and at the end of the day love each other. She doesn't care what others have to say about what she's wearing or what her hair looks like.
White Boy 1: Man, did you see Erin today? She's smoking!
White Boy 2: Yeah those lucky black guys! If only she was a not a night rider!
