n.丘疹；脓疱；疙瘩；粉刺
The pimple came to a head before bursting. 丘疹长成脓包後才破裂。
This statistic still does not make it any easier when you look in the mirror and a big pimple stares right back at you. 但是当你面对镜子时，如果一个巨大的丘疹在里面盯着你，这种数据丝毫不会让你感到轻松一些。
A line-end node will not vary much, so it will not appear in front of a pimple. 一股线结的结不会很大，所以不会在前面显出一个疙瘩。
adj.[医](=pimply)有丘疹的；多粉刺的
