are you a herbivore or a carnivore?

Herbivorous men [sōshoku danshi - 草食男子]:

Coined in 2006 by author Maki Fukasawa, this term refers to an emerging breed of man whose passive nature stands in stark contrast to conventional notions of masculinity. Typically in his 20s or 30s, the herbivore doesn’t earn much money, spends little, takes a keen interest in fashion and his personal appearance, and does not aggressively pursue “flesh” (i.e. romance and sex). Friendly and home-oriented, he tends to favor cosmetics over deluxe cars and would rather eat sweets at home than treat his girlfriend to dinner at a fancy restaurant.

Herbivorous/carnivorous [sōshoku-kei/nikushoku-kei - 草食系／肉食系]:

Where the herbivorous man is passive, the so-called “carnivorous woman” is aggressive. The words “herbivorous” and “carnivorous” have come to denote one’s level of passiveness or aggressiveness, particularly with respect to sex and romance.
