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.

Get the Younger sistermug. An annual sickness that befalls lovers of craft beer during Russian River Brewing's annual release of Pliny the Younger. Symptoms include uncontrollable thirst, standing in insanely long lines, talking to no end about how amazing Pliny the Younger is and how all other beers are just practice runs during the off season. Younger Fever can be spread through blogs, bragging, and memories of previous Younger.
There's no use offering him a beer, he has Younger Fever. Nothing will make him okay until he find the Pliny.
