The Sister Switchero 

A limpy wristed fag that dresses like a girl while attending the gay pride parade.

Gee, that cross dresser is confusing. It looks like he's been confused by The Sister Switchero.

Younger sister 

You’ll have to forgive her for how annoying she can be, but deep down she knows she’s gonna end up all alone when she’s the last one left. So who gives a F*** about younger sibling privileges?! She deserves them all for the pain she will forever deal with.

You may not see this pain and r probably thinking rn this certain younger sister doesn’t have any…SHE DOES! She’s just an incredible actress. She felt the pain when you got double booked on the day u were supposed to meet. She felt the pain when you couldn’t go on the family holiday. And finally she felt the pain when you were out partying and she was left alone, again, and finds herself once more crying herself to sleep.

She cares so much more then you could ever comprehend. I promise you, cos I am that younger sister.

Younger sisters friend: U coming to the biggest party of the year with us??

Younger sister: No, sorry have plans with my sister! *goes to arranged meet up spot
——————————————————————-
Big sisters friend: You coming clubbing for the 3rd time this week with us??

Big sister: Umm…yeah why not? Let me just text my lil sister, she won’t mind.

Younger sister: goes home, cry‘s, doesn’t tell her sister how she feels, repeat… 💔

The Sister Switch (T.S.S)

The sister switch also know as the roomate switch because it applies to roomates and sisters. You find out your girlfriend’s sister/roomate is the more desireable one and you want to switch. How you do it is you suggest a threesome with the sister/roomate to your girlfriend and she is so appauled by the idea she kicks you out. She later vents about to the other and she is secretly flattered why giving fake sympathy. You wait until you girlfriend is at work and you call the sister/roomate. You get past the awkwardness then you ask her out.

There is an alternate scenario where your girlfriend is into it and the sister/roomate is too. In this case you either are very lucky or offered to aide in incest where you are expected to decline.

S6 EP12 of Seinfeld Jerry attempts The Sister Switch (T.S.S) with his girlfriends roomate and gets offered threesome and declines because he’s secretly gay.

Younger sister 

The baby your mom gave birth to who isn't you. The one who is sometimes a curse, and sometimes a blessing.

Person 1: My younger sister photobombed me and now it's a meme, and a sticker!

Person 2: It's a gif, too!

Person 1: Oh boy, there goes the rest of the schoolyear.

Person 1: Who spread this rumor about me!?!?!?

Younger sister: Kat!

Person 1: Thank you! I'll tell her to take it down.
