An extremely handsome and highly intelligent guy. A Liam is never to be underestimated. Though at times a bit of a badass and tough around the edges, he has a soft and sweet inside. Beware though, because he is a definite lady's man. A Liam breaks many hearts without even trying. Liam's are also highly artistic and musically inclined. They can accomplish anything they set out to do.
Woah.. you better watch out. That's a Liam you're talking about.
