Mep is used to when describing the sound made when in rush. Often heard in crowded areas, and occasionally heard in public areas like roads, pavements, banks, parks etc. It is also often heard when near groups of animals, especially birds. Commonly mistaken for murmuring. Used interchangeablely with Meep.

It is generally the sound that babies' hear and interpret when someone is talking to them or to someone else.

It's exact definition and origin are unknown, however several sources point to it being the contraction of the word 'Meep', while others say it was originally an onomatopoeia of the sound that the Roadrunner made in the popular cartoon 'Wile E. Coyote and the Road Runner'.

Just a way to express something funny, or you can say "mep" for fun

1. unclear response to a rhetorical or stupid question aimed at passing the baton back to the other speaker
2. used to express intent to talk, though without indicating purpose
