face shaker
A face shaker is when you burp so loud and so long that it feels like your face is being shaken by a monster, and your whole body is trying to escape.
My dad burped so hard during dinner, the dog ran out of the room.
At the gym, I let out a face shaker so loud, the weights shook.
During my friend’s birthday party, I burped so hard, the cake fell on the floor.
