A word from Irish origination, meaning "filthy, unwashed male genitals." This may also mean "man who conducts sexual intercourse with animals, particularly sheep."
1: I saw that guyfucking his neighbor's sheep!
2: He's such a Rowan!
Rowan is what you would call an annoying female and is usually one of your best friendssister. These people are usually very rude and never wears socks and just wears pajama bottoms. Is you ever see one in public, run.
Me, "Bro there is a Rowan in my school, I hate her."
Rowan is the girl I love. Rowan is the most beautiful girl in the world. Rowan can make your world light up in an instant. One day I wanna marry rowan. I love her with all my heart, and I’m never going to stop loving her. No matter what we go through I will always love her. She can make me laugh even when I’m at my lowest. She’s always there for me, and even puts her feelings aside for me. I couldn’t ask for anyone better, and I’m so happy to spend my time with her. There’s no girl I would rather love than rowan. Rowan, will you be my valentine?
