Yonkers (Yo-nk-ers) 

Also known as Yonk Daddy. This has been a nickname for many fellow Yonks. The Yonk community usually has side effects of random spazzing of the Yonks and my rub off on any of the Yonks friends. Some people who do not know how to pronounce Yonkers may use one of her other names such as yonkeee and Yonkauis (Yonk-ali-us). If you do spot a Yonkers it is usually a once in a lifetime opportunity for they are a rare and wild species. One way to avoid a Yonk is to hang around a strawberry field. One way to attract a Yonk is to dress up as a purple power ranger just because. Now one thing you have to remember about Yonks is that every single one of them have a birth name but they are all called Yonks as a cult.

person: "Omg Ella is it just me or does she not act just like a Yonk???"

Ella: "OMG I thought it was just me...well if we listen we might be able to hear her Yonk...that is if she is a Yonk".

Fellow Yonk: *Yonk Yonk Yonk*

Purple Power Ranger: *runs into strawberry field*

Yonk: *runs away hissing*

Ella: "OMG she is such a Yonkers (Yo-nk-ers)
