There's this psycho named O'Donnell
Who's brain is obviously not well
She now threatens POTUS
The Secret Service must put her on notice
One more threat and she'll be in a cell

Good idea, but here are some limerick rules to help

There’s a psycho who’s called “Rosie O”
Who keeps screaming that Trump’s gotta go
And her head you will find
In her monster behind
And from there we see her BS flow
