It is the first time I hear about that game, but I am encouraged to participate, I always keep my essence as a child 😊:
Cough- For me it would be the arabica coffee, which from my appreciation is too soft and with a much higher level of acidity than the rest
Hug- I would embrace my soul with a delicious coffee with cinnamon!!!!
Marry- I would say: "Yes, I accept you" to any strong espresso coffee.
Kill- Any variety of coffee that contains too much sweetener, I feel that in this way the coffee loses its essence, its flavor
