The guy who you've known since you were 9 years old and you will still be crazy about when you're 99 years old. You probably met at a Little League baseball game and before you knew it you were going to prom together. He's a little obsessed with computers, maps, and food... but you love him for it. There's no other person in the whole world who you'd want to be with when in their car singing to billy or james for hours on end, or laying in bed doing nothing for hours and not getting bored, or surviving grandmothers singing at their own 80th birthday parties, or heavens! driving past cows for over an hour to a closed damn museum, or surviving crazy friends who you're not even sure why you're friends with in the first place, or riding bikes with to Carvel when you're 18 years old, or exploring houses still in construction and having fun in the attic, or blacking out on new years together, or having the best night of your life going to nyc and riding a bicycle cab, or driving 8 hours just to see their cute face for a day and a half, or talking to them everyday just to hear their voice for a little bit. Basically you're crazy about them and can't even express it in words. That's Danny Boy for you.

Danny boy is a boy that made you feel comfortable right away, a person that you can share everything with and know that they wouldn't judge you. A person who knows what your thinking by just reading your expressions or looking into your eyes. Someone that you can talk to for hours without getting bored. The sweetest guy you'll meet.. that's a danny boy.

Danny Boy

Old Danny Boy is some one who at a young age aspires to be a wise old man. Everyone has a Danny Boy in their life. He will most likely be a registered sex offender for intimate relations with a young girl. When Danny Boy is ever called out on his bullshit or outsmarted, he responds with an irrelevant and absurd statement.
Example:1
Friend: Danny Boy have you ever driven a truck.

Danny Boy: Yeah I have! Ive driven an f250 Cummings.

Friend: Danny Boy Ford does not use Cummings engines.

Danny Boy: You want me to rip the foreskin off your dick and feed it to you.

Example:2
(Danny Boy at a bar)

Danny Boy: Bartender, Ill have a scotch.

Bartender: You're not having anything, you are clearly not 21.

Danny Boy: I'm going to bend you over and take you down to brown town.

Bartender: Excuse me.

Danny Boy: you heard me right, brown town. You don't give a man a prostate exam without using butter.
