face shaker
A face shaker is when you burp so hard that your face turns red, your eyes almost pop out, and you look like you just got hit by a truck.
At the pizza party, my cousin burped so hard, he looked like he was about to cry.
During lunch, my little brother let out a face shaker that made the whole table laugh.
I burped so hard during my Zoom meeting, my boss thought I was having a heart attack.
