The most versatile word in the English language, or in fact any language!

Can mean whatever you want it to mean, but the most popular uses are:
1. An exclamation akin to 'ouch' or 'uh oh..'
2. Filling in the blanks where other (rude) words would go.
3. A greeting! I personally say meep instead of Hello...
4. A random expression of happiness used to fill gaps in conversation.

Meep is the best word ever! Meep!

Isn't it the sound that Beaker from the Muppet Show makes?

Onomatopoeia, one of surprise, akin to a gasp.

Meep : Sums up everything.

An exclamation which can be used for any purpose whatsoever.

Interestingly enough, the religious sect 'The Followers of the Meep' regard the use of the word Meep by any non-Follower as heresy.

This is a word which is used when you are at lack of what to say or just wish to say something random. It's sure to make an impact.
