Twentieth Century 

1. The ~ Limited, an extinct luxury train from New York to Chicago.
2. Hell on Earth, 1900-1999, or 1901-2000, for would-be purists.

In the Twentieth Century fools prated of progress, and mass murder was an athletic event.

twentieth base 

The final base.
When a guy fucks another dead guy through his penis hole while being penetrated by a shemale

Friend 1: Yo, I heard you and Josh got to the twentieth base last night at the funeral. That's fucked up.
Friend 2: I regret nothing.

twentieth century bathroom

A public restroom missing so much as ONE of these 21st century features:
1. Infrared automatic faucets that stay on as long as you are moving your hands
2. Automatic hand dryer and/or automatic paper towels
3. Self flushing toilet/urinal
4. Automatic soap

Don't go in that McDonalds down the street if you have 7 year diarrhea, they only have a twentieth century bathroom.

When you want to get DOWN to some jazz but you ain't got Spotify Premium so you gotta wait for that good shit on your playlist.

"Damn man, it's a shame I can't get down tonight. I've got some Twentieth Century Blues."

Mid-Twenties Breakdown

A time of mental breakdown that occurs during a person's twenties, often a result of an inability to function outside of college/university or other types of structured environments. Feeling alone and/or useless also tends to be a symptom of the mid-twenties breakdown.

Soon after Paul finished grad school at age 24 he found that he couldn't get a job and had a mid-twenties breakdown and moved back to his parents' basement where he spent most of his days playing Xbox and smoking weed.
