龇牙咧嘴 grimacing face

含义说明

整排牙齿僵硬地露出来、眉毛皱成八字，像被逼到墙角硬着头皮笑。答应完突然发现做不到、deadline 比想象紧、被当众点名，发它表示「我人在这但很尴尬」；临时被拉去开会、在群里被 @ 回答答不上来，它就是你的救场表情。情绪强度偏强烈，主打紧张尴尬，是「强颜欢笑」的具象。与 😅 的区别是 😅 是挂着汗的礼貌笑，😬 是咬牙式的僵硬，更接近内心崩溃；与捂眼偷看的区别在于它是直面尴尬、无处可躲。救场必备，尴尬时甩它准没错。

A rigid grin showing clenched teeth with furrowed brows is the "I am in trouble but I will smile through it" face. It reacts to an impossible commitment, a scary deadline, or being put on the spot. Its strained, clenched quality differs from the polite sweat-drop smile of 😅; it is about visible awkwardness, not covert nervousness.

网络流行义在群里回复「这个 deadline 有点紧」常配它。
