Riwoo's new hairstyle is a hit

In the Korean comments

Several comments call the pair 두부즈 (dubuz, “the tofu duo”). One reads, in translation, “They look like seasoned tofu and slightly grilled tofu,” while another calls them “golden-browned tofu” and says their dance lines offer two different “flavors.”

What the words mean

리듬을 맛있게 타다 (ride the rhythm “deliciously”) is not about food: it means grooving in an especially satisfying, stylish way. Likewise, a comment saying RIWOO 잘 소화한다 (literally “digests it well”) means he pulls off a hairstyle that is difficult to suit; both are casual, emphatic compliments.
