How DONNA CHENGstein mispronounced 'ridiculous' on the greatest sitcom ever, Seinfeld. It wasn't Elaine and you should be ashamed of yourself for thinking so.
Donna: This is really getting ridicurous!
Jerry: ..........Did you say 'ridicurous'?
Donna: Ridiculous!
jerry: I thought you said... 'ridicurous'...
When things are getting so rad that the levels of rad are surpassing the levels of gnar. Resulting in Radaculous (typically a term used amongst skaters)
