The inflammation of a Millennial. The presence of any discomfort or pain that is unwanted in someone feeling entitled to life without pain. Pain can manifest as physical symptoms or emotional distress, brought on by such conditions as the "common cold" or a "differing opinion". Typically found within the Millennia Generation, this dangerous condition is also contagious to non-Millennials feeling similarly entitled, and can be referred to "Millennieitis by Poxy".

A millennial who reads all the y.a. books they can find on their kindle; reads all the books that are literal straight porn.

A person who is a member of the Church of Jesus Christ of Later Day Saints, but only follows the rules that are convent to their lifestyle. A jack Mormon, but with a fancy haircut.

Behaving like an individual who avoids the behaviours expected of a responsible and mature adult. Sarcastically used by adults regarding behaviours (or lack thereof) demonstrating a lack of maturity by millennial's who sarcastically use adulting to validate moments of maturation.

A tragic digital condition in which a millennial’s sense of humor, creativity, and critical thinking slowly decay due to prolonged exposure to low-effort, painfully relatable, nostalgia-bait content. Often triggered by watching 30-minute reaction videos, BuzzFeed-era skits, or “adulting is hard” jokes for the 800th time.
Symptoms include:
Saying “This is so me!” to TikToks about doing laundry.
Thinking quoting The Office counts as having a personality.
Commenting “he doesn’t miss” under a guy reacting to 60 TikToks in silence.
Wearing shirts that say “I can’t adult today.”
Cry-laughing at wine jokes that haven’t evolved since 2014.

Millennial is a word that is used by most Boomers when they're actually talking about a Snowflake. A Millennial was born anywhere from 1981 - 1996.
Robert the Old: He must be a Millennial cause he talks like one of those ignorant people born in 1999.
