When someone is wearing clothing that is too tight and their fat is pouring out over it. (They don't fit).
I was at the pool with my friend, we thought this lady was topless because we couldn't see any strings to her suit. It turned out they were under her fat. She was a whale in a mud puddle.
When a woman is wearing jeans that are so tight her fat is pouring out over them.
Eww! Look at that lady, she is like a whale in a mud puddle!
People that are so big that they shouldn't be swimming. Especially in a tiny lake!
Look how much space she is taking up, there is hardly any room to swim, she is such a whale in a mud puddle!
