Sisters, especially the younger ones, are big-time copycats. While that’s a compliment to you, copying your fashion, hairstyle, and everything else can get to you sometimes. But guess what younger sisters do not like? Calling them a copycat! This way you will not only name the lady appropriately, but it can also discourage her from copying you.

8. Booger

Does your sister pick her nose too often? A funny nickname for your nose-picking sister would be “Booger”. Teasing her with this nickname will help you both have a little game of tag and laughter – just how siblings play-fight.

9. Geek

With her big glasses, always in the library, sleeping on an open book, and having answers to all your questions – your sister has all the signs of a geek. Nicknaming her “Geek” would therefore be apt for your sister.

Do you always find her on the couch in a sitting position? Well, she can work, read, or be productive, but making the couch her study and bedroom can be annoying. Instead of bickering, nickname your chick a couch potato. That’ll do the trick (wink!).

12. Brat

Younger sisters are often spoiled by their parents. They need attention all the time and want their demands met by hook or crook. If your sister is also spoiled, Brat is the perfect nickname for your broski.

13. Lilliput

Do you have a naughty baby sister who is a 24/7 goof? Or, a sister who is a tad too short compared to you and does all sorts of notorious activities to tease you and seek your attention? The nickname Lilliput is perfect for the sissy, who loves to be around you and has a ton of curiosity.

14. Plum

Do you have a sweet sister who is moody and gets upset a little too quickly? If your sis is sweet and sour, but you love and adore your sister for being so true to who she is, Plum will be an ideal nickname for the kin sister.

15. Genius

Is your sister extremely talented when it comes to studies or sports? Nickname her “Genius”. However, if your sister is just the opposite of a genius, calling her Genius can be a Chandler-like humorous move.

16. Nugget

Nugget is the perfect nickname for a loving sister who is super cute, a goof, and downright adorable. Whether you mean her to be a “nugget of joy” or an “adorable nugget”, it’s a cute name – just the one you are looking for your baby sister.
