少儿不宜啊，你自己去看看吧。是在XXX的时候出现尴尬的声音。

queef：is an emission or expulsion of air from the vagina, often during or after sexual intercourse or (less often) other sexual acts, stretching or exercise. The sound is somewhat comparable to flatulence from the anus but does not involve waste gases and thus often has no specific odor associated.

XXX后释放天然气。
