B.F.T.D.S.
B. F. T. D. S. is when you get so fat in your 20s that you look like you’ve been stuffed into a backpack and left in the sun.
I got B. F. T. D. S. from eating burgers every day. I now look like a burger myself.
My friend has B. F. T. D. S. He can’t fit into his car anymore.
My dog got B. F. T. D. S. from eating my leftovers. Now he’s a walking meatball.
