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
Person 1: Check out this dank ass weed I got for the party tonight
Person 2: Deaummmmmmm foo that's tight!
(Ghetto girl with a hint of B.O walks in)
People in the hallway: Deaummmmmmmmmm
