Twinkle Twins 

Someone who shines extra sparkly. Particularly on the day of their birth with another human who also sparkles brightly on the same day.

Not to be confused with: "sparkle adjacents", "shiny duplicates" or "firework friends".

"That Carly Rae Jepsen is twinkle twins with that dashing human resources manager I know." "You mean they share the same birthday Ted?" "Yes Bob." "Just say that next time...instead of sounding like a f#%$n idiot." "Dually noted Ted - dually noted."

To Twinkle Twin: Ignore Ted and proceed rejoicing in the Sparkle of shared birthdays.

twinsie 

A picture taken of just the two of you and your friend, you and your significant other, or you and someone else with the intention of uploading directly or manually to Instagram, Facebook, Twitter, Tumblr, Pinterest, Myspace, Vine, and any other similar social networks or photo upload capable website.

Both of you will be mirroring each other's acts, poses, silliness, or facial expressions as if twins. One of you will be usually holding the camera with your arms stretched out to take the picture (part of arm stretched out can usually be seen in pictures taken).

At rare occasions, twinsies may be taken using a tripod or through the help of a passer-by.

1. "Hey wanna take a twinsie? Just you and me, with the sunset in the background?" "Sure! That'll be great for our date photo!"

2. **hmm I should take a twinsie with my girl to replace my selfie on Facebook.**
