look up any word, like fleek:
Name for the Meat Packing District in downtown New York City. Used as a nickname by trendy 20 and 30-something Manhattanites to describe this Bacchean playground of wealth, beauty, trend and youth.

You can't wear that, we are going to MePa tonight!
by D Brotha November 27, 2007
Someone who loves you with all their heart even though they're not related.

A person whose importance to life cannot be described by mere words, but only in song of unknown language.
A person that is never far from your thoughts.
P.S. This should be in a real dictionary.
You have to know a MePa; you can't find her on a babysitter website.
