Huh?

Momma had a laughing, wheezing, crying fit today. She was looking at this on her phone and we aren't sure if she's ok or not. Check it out!

Yo momma so big, she wore a tight pair of yellow pants and bent to pick up a quarter. Three guys got in. Thought it was a yellow cab.

(we don't get it. Why are you laughing, wheezing and crying?)
