What is a Liam? from the urban dictionary
A Liam is an amazing character, if you're ever lucky enough to meet one. Not mainstream, not even so ridiculously anti-mainstream that he's mainstream, (*cough* hipsters), but he's a genuinely amazing person, and a great one to have as a friend. If you love a Liam, you're a lucky person. If a Liam loves you back, you're even luckier.
Liam's tend to be hilarious, open-minded, modest, loveable, respectful, and sees all the amazing things about you that you don't. Unfortunately poor Liam doesn't see the amazing things about himself, so you might need to help him out.
Liam's are also ladies-men. This, is always a plus
