A guy who keeps blowing smoke up his own arse on Urban Dictionary.

To miss an opportunity that’s right in front of your face

A Matt (or just Mat) will make the best boyfriend/guyfriend ever. With their big brown eyes, and heart-melting smile it's hard not to fall for them. They are different, in a beautiful way. Even though they've had a bad past, you'll never know it. They are really strong people, and they change for the better. They are there when you need them, and they value their friendships. They like to look good, and dress well. Handsome, and charming. Very successful at life, make great Dads. Known to be players but when they meet that special girl, their sold. Matt's come off as tough and solid, but deep down, their soft side comes out and you see the sweet gentleman in them. They're not popular, but not a loner either. Friends love them, and guys want to be him. They have a really laid back attitude about themselves, but at the same time they can be the life of the party. Even though they can be a jerk at times, they mean well and are really the nicest guys ever. If you have a Matt, don't let him go. None other compares.
