Something so loud that defies any sort of
good explanation as to why it has to be that loud.
The term can can be used in a couple of situations with different connotations:
1. When someone or
something is very loud when they/it does not need to be. Similar to needlessly loud.
2. To describe a thing that naturally has a very, very high decibel level.
1. SHUTUP! You're talking so stupid loud that I can't
even think!
1a. Why do you have the TV on so stupid loud? You can hear it from across the damn street!
2. Holy
shit, lightning struck the
tree in our yard last night and the thunder was stupid loud!
