spitnik
When you underestimate someone's capabilities and spit at them thinking that they are the biggest delusional fools you have ever come across & then they prove their worth & you realize what a jackass loser you've been all your life who will amount to nothing & that people won't even bother spitting on your grave. Derived from Sputnik, Russian satellites.
Some Russians launched spitnik on Elon Musk's face when he tried to buy missiles from them for $4 million a piece.
