turtle underwear

To be wearing underwear that are very disgusting, often having a horrific odor and be very hard like a turtle's shell.

Adrian - Dude, Bonnaroo was really fun, but sleeping in your car wasn't. I'm wearing turtle underwear.

Netflix underground

Watching unknown, hidden gems on Netflix. The type that wasn't in theaters but is highly relatable, fucked up, and funny.

"What's your Sunday looking like right now?"

"Just laying on the couch hungover. Probably watching some Netflix underground involving sex, drugs, and regret. Basically my night last night,"

"OMG I'm coming over. I found Strictly Sexual. Total Netflix underground gem."

hicks underground library

Hicks Underground Library is a place at Purdue University. From the outside it looks small but is actually quite large inside, much like the TARDIS from the show Doctor Who. Its is a popular place for students to go and study with friends.

Student 1: Have you ever been to Hicks Underground Library?

Student 2: What do you mean, 'have I been there'? I practically live in that place!

IQ Underdevelopment

When your IQ is apparently 'lower than current age standards' of your peers in your age group.
In short, nonsense about your IQ and how dumb you are.

Me : "According to my test IQ results, I have 'IQ underdevelopment'."
Human 2 : "Now, why isn't that surprising mate "
Me : F*** you !
