Another spelling of the word "wat." Used in response to an unclear or absurd statement when seeking to clarify it or expose said absurdity. Commonly used on internet message boards or online games, the word was originally used in 1337 speak and chat language, but has since been used humorously in many cases.

The safeguarding of Earth and other worlds from biological cross-contamination (i.e. billionaires with too much time on their hands).

Also known as “planetary protection.” Planetary protection / quarantine “reflects both the unknown nature of the space environment and the desire of the scientific community to preserve the pristine nature of celestial bodies until they can be studied in detail.”

There are two types of interplanetary contamination. Forward contamination is the transfer of viable organisms from Earth to another celestial body. Back contamination is the transfer of extraterrestrial organisms, if such exist, back to the Earth's biosphere.

A shorter variation of "What." Something someone says when they are baffled or confused.

1. An expression similar in meaning to the word "What"

2. A "leet" word for what

3. A remark most commonly used after a party has told a ridiculous/unbelievable story. after a pause the listener responds "wut" or "lol wut"

This can be considered a shortened form of 'what' but for some, simply using 'wut' and nothing else as a response shows somethings stupidity. Saying 'wut' after a response or something that someone has said that doesn't make sense is like saying 'huh?' really sarcastically.

Essentially the same as "what", just the way weird people spell it.

In a certain remote village of Idaho, its inhabitants use it to mean "what the heck, that's so unfair, I can't believe it"

A typed version of the word "what", for use in response to things that are too ridiculous, retarded or out-of-the-blue to deserve a regular, correctly spelled inquiry. Great for Youtube conversations.
