Top definition
A word used to express someone's shock or amazement in cases where the regular "Damn" won't do. Can also be used to express disgust (when a fat/ugly/ghetto bitch walks in the hallway, for example)

Extra m's can be added or removed from the end of the word if the user wishes to provide more emphasis
Example 1)
Person 1: Check out this dank ass weed I got for the party tonight
Person 2: Deaummmmmmm foo that's tight!

Example 2)
(Ghetto girl with a hint of B.O walks in)
People in the hallway: Deaummmmmmmmmm
