d-bagapalooza
A bunch of people who think they're cool but are actually just loud and dumb.
My friend's birthday was a d-bagapalooza. Half the guests didn't show up, and the music was too loud.
That restaurant was a d-bagapalooza. The waiter spilled my drink and called me 'buddy' five times.
The mall was a d-bagapalooza. A kid cried because he got the wrong color shirt.
