Meep can be used to describe any emotion. It's less of a sound and more of a vibe, so its definition will depend on the person using it. It is also a very nice word to yell if you are stressed. Common uses include:

1. Manner to avoid conversation
2. Manner to get attention
2. Expressing emotion of alarm or angst
3. Expressing emotion of discomfort
1. Mom: Did you do the dishes?
Son: meep.

2. Child: Meep!
Mother: Yes sweetie?

2. *sees guy approaching with a knife* MEEP!! O_O

3. Susie: Hey, you know we have 2 labs and 3 assignments due tonight, right?
Amanda: Yep! It's fine! Haha! Meep!

Bonus Scenario: Mimi has been stressed out for her final exams the entire day. She looks around to make sure nobody is there to hear her, takes a deep breath, and screeches "MEEP!!". She suddenly feels like it will be okay, because she let out all the pent-up stress.

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!
1. "HEY GET BACK HERE!!!" "Meep!" 0.0
2. "Ahh.. Meeping Hell!" >.<
3. "Meep." ^.^
4. "....meep...." ^__^

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.

The Great Meeper said, "This non-Follower has committed the grievous crime of Meeping without a licence."
