To come down with the flu.

The term originates in the US mid-south, possibly in Arkansas or Tennessee. It is a supposed combination of the words "flu" and "flown". To "flune away" is to recover from the flu.
"I'm afraid he flune."

"They flune him at work so he gonna call in sick today."
"He flune away!"
"I hope I don't flune!"
