Derived from the French term dejavu (which is when one feels that the experience s/he is going through is exactly like an experience s/he has gone through before), dejaboo is when the experience is UNPLEASANT.
Yesterday I was walking back to work with my Big Mac when I realized that I'd seen this exact same scene so many times before. And it wasn't dejavu--it was dejaBOO. I've been working as a clerk at the same firm for 25 years, & have eaten the same thing for lunch. BOOOOO
Is the experience of feeling sure that one has already witnessed or experienced a current boob, even though the exact circumstances of the previous encounter are uncertain and were perhaps imagined
It is said of the situation where a person has the bad luck to make contact with his testicles against an undefined surface or object, intentioned or not.
Given the nature of the word, it is more appropriate to design cases where the interaction is made with a moving object, for example, a ball.
Although it is extremely painful for the victim, it tends to be considerably funny to people who witness it.
Today in the baseball game the pitcher took a nutshot; the baseball hit him in the nuts.
Man, I just watched the funniest nutshot video ever.
