laftermath
The time after you laugh so much, your face looks like a balloon
The joke was so good, I laughed until my face looked like a balloon. The laftermath was my cheeks glowing like a lava lamp.
He told the punchline, and I laughed until my face was red. The laftermath was me looking like a tomato.
She made me laugh so hard, my face turned into a balloon. The laftermath was me bursting with joy.
