sticky rice
n.— «There are some who are “international buffet,” most of the rest are “sticky-rice,” i.e. East Asians who go for East Asians. They too can be quite specific about their tastes, and even if they think hard about it, they can rarely explain why they find fellow Asians a lot more attractive» —“Rice and Potatoes” by Au Waipang Yawning Bread (Singapore) Dec., 1996.
