Imagine your waifu is spoon feeding you the most delicious cake you've ever eaten, then she pulls off her mask and it's Mike Tyson who shoves horse crap in your mouth.
Imagine you just won the Nobel Prize it's the greatest moment of your life, you open the curtain to walk out and you find yourself in a dark cinder-block room with the mafia who start beating the crap out of you and spiting on you.
