Urbandictionary was surprisingly lacking a definition for badabing badaboom, then badabing badaboom! here it is!
Badabing Badaboom is a slang phrase which is similar to the French term "Voila". By using badabing badaboom as an expression you are assuming that others get a generalised sense of the steps in a story you left out.
The guy accidentally spills her drink, he appologises and badabing badaboom 6 months later theyre married.
Often interchangeable with the term "one thing leads to another"
There was already an example of "badabing badaboom" on urbandictionary but people were luke warm about it so badabing badaboom I write this new definition
