If you consider yourself a nerd, you've probably seen "Doctor Who." If not, you've probably at least heard of it and think to yourself daily, "I should watch that show." Because you really should.

However, if you know absolutely nothing about BBC's "Doctor Who," you may be a little bit behind on the times on the fandom's vocabulary. Maybe you find yourself lost in conversation with "Doctor Who" fans and wonder to yourself "What do you mean stone statues of angels are terrifying?" If you find yourself doing this, then maybe this article of 13 words that means something slightly different to "Doctor Who" fans than the normal person is for you.

1. Banana

Normal People: A yellow, potassium-rich fruit.

"Doctor Who" Fans: A great replacement for a gun or sonic blaster. Used for banana daiquiris, which the Doctor accidentally invented several centuries early at a party in 18th century France. The best advice ever: "Always bring a banana to a party."

2. Time

Normal People: A system of sequential relations that any event has to another, set as past, present, or future.

"Doctor Who" Fans: Time is complicated. People assume that it's a strict progression of cause to effect, but really, from a non-linear, non-subjective viewpoint, it's more like a big ball of wibbly-wobbly, timey-wimey stuff.

3. Weeping Angel

Normal People: Angel statues often seen in graveyards. They appear as if they're crying.

"Doctor Who" Fans: An extremely powerful race of humanoid creatures that send their victims through time, feeding off of the potential time energy from the lives that their victims should have led. They keep their hands over their faces to avoid petrifying other weeping angels by looking at them. Weeping Angels can only move when no one is looking at them.

4. Silent

Normal People: Making no sound, quiet or still.

"Doctor Who" Fans: Genetically engineered priests of the Church of the Silence. Anyone who sees the Silents immediately forgets them upon looking away.

5. Pond

Normal People: A small body of water.

"Doctor Who" Fans: Amelia "Amy" Pond is the first companion of the 11th Doctor. Otherwise known as one of the many characters you never got over.

6. Christmas

Normal People: A winter festival of the Christian church, celebrating the birth of Jesus.

"Doctor Who" Fans: The one time of the year that you want to be anywhere but London, England. Maybe then you'll avoid killer Christmas trees, robot Santas and replicas of the Titanic falling from the sky. Christmas may also refer to the small farming town on the human colony, Trenzalore, where a truth field makes it impossible for anyone to tell a lie.

7. Screwdriver

Normal People: A hand tool made for turning screws.

"Doctor Who" Fans: Something that could possibly be a little more sonic. A high versatile tool, the Doctor's sonic screwdriver can open the lock of nearly anything, except wooden doors (because wood is too primitive).

8. Companion

Normal People: A person who frequently accompanies another.

"Doctor Who" Fans: The Doctor's closest friends. They provide the Doctor with company and often stand as his voice of reason to prevent him from abusing his powers.

9. Jelly Babies

Normal People: An English sweet made of gelatin and available in a variety of colors and flavors.

"Doctor Who" Fans: A favorite sweet of the 4th Doctor. He often offers them to his companions, as well as to others that he meets on his travels.

10. Regeneration

Normal People: The restoration or new growth by an organism of organs, tissues, etc. that have been lost, removed or injured.

"Doctor Who" Fans: The process by which Time Lords renewed themselves, causing a complete and often psychological change. The regeneration process can happen due to sickness, old age or injury.

11. Bow Tie

Normal People: A small necktie that's in the shape of a bow at the collar.

"Doctor Who" Fans: Possibly the coolest men's accessory ever. In fact, it's right up there with fezzes and stetsons.

12. K9

Normal People: A dog.

"Doctor Who" Fans: The sassiest, most adorable metal box ever. K9 is an intelligent, dog-like robot, programmed to be loyal and logical. He is most well-known for his time with the 4th Doctor and his companion, Sarah Jane Smith.

13. Doctor

Normal People: A person licensed to practice medicine.

"Doctor Who" Fans: The last of his kind. The Doctor is a renegade Time Lord, an ancient alien race with the power to travel through time and space and regenerate, who "borrowed" a TARDIS from his home planet and ran away. He has a deep love of Earth and protects it as much as he can. The biggest question of the series: Doctor Who?
