look up any word, like cleveland steamer:
 
1.
A word shouted to fill an awkward silence and or just to say for no reason. Said repeatedly for no reason such as Tourettes.
If you are walking by someone on the street and feel the need to say something, just yell decchia!

Or in an awkward silence ask loudly, "Is DECCHIA there please?"

In the case of mild Tourettes someone would say "de-DECCHIA there!"
