Dejagoo is the strange feeling that you've been in this sticky situation before. It is dejavu due to goo. Usual symptoms are shivers down once's spine followed by disgust, especially if actual goo is involved.
Dude I like just like stepped in doggy doodoo. And i was like, oh dude this feels familiar. Then I remembered that I like stepped in pup poo like last weekend too. Surreal man, it was like total dejagoo.
