Definition:
An exaggerated form of ridiculous, often used to describe something absurd, excessive, or hilariously over-the-top.
Origin:
Coined by coworkers Tim C. and Serge H., who used to joke that ridiculous things were “like a donkey.” This led to the blend ridonkulous, which became a staple of their office slang before spreading to a wider audience.
“That outfit is ridonkulous—in the best way possible.”
“Dude, the traffic today was ridonkulous.”
