Haha. White monsters are pretty popular with gen-z'ers in general. A lot of us don't like coffee but still want a hit of caffeine and it's basically pure caffeine with a very mild taste. Other sugar free energy drinks have a much stronger sourness (red bull) or more distinctive flavours. I do love the tropical and coconut red bulls though.

The green monsters are definitely more male gamer oriented, but the white, green, pink, rose monsters etc seem pretty popular with people in my generation who fall outside that male gamer demographic.

Personally I prefer red bull now but as I get older I mostly drink coffee.
