The meep is an interdimentional being that is undefinable by any human measurement. However it manifests itself as a head with a huge smile and special ears. It also wears a spotted party hat. The earth, and everything, was created by the meep. After he was finished, he smiled from ear to ear and put on a wonderful party hat. The meep simultaneousely watches over everything and everyone on the earth and throughout the many universes under his jurisdiction. The meep has a strict moral code, wich can be summed up by three letters arranged as points on a triangle surrounding his beutiful head. These letters are H, D, and S. The Meep stands for happiness, drugs, and sick beats.
Larry's Gorgeous Girlfriend: I love jesus 4 life! Jesus is x-treme. He offers x-treme salvation through x-treme repentance for awesome sinz!

Me: Fuck you bitch, I'm representing the meep. He stands for hapiness, drugs, and sick beats. He doesn't give a shit about anyone! He loves life, and himself.

Larry's Gorgeous Girlfriend: Yeah, whatev. I hate all those things, especially hapiness. It makes me feel unclean.

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.
