a little man who likes to flex his muscles and brags about the fact that his mum is a dentist and that he is rich because his mummy is dentist. he also has many girlfriends that he tongues with in front of all his friends but he doesn't do it in front of his mummy because she will beat him because he is not old enough to date (he is 15).
random man: look there Declan wonder when his mummy is gonna let him date
Declan: don't talk shit about my mummy

A boy who gets on well with girls, but is often mistaken to be gay. No one ever knows if Declan is, but the boys think so.
Girl: Declan is a great friend!
Boy: You know he’s gay, right?

A Declan - a supporters of British football club Celtic FC, who claim to be Irish based on the fact that their grandmother once bought a Riverdance CD.
Also known as a "Plastic Paddy" they are to be found in small numbers in the bheast end of Glasgow, singing songs in support of the child murdering Irish Republican Army ( now deceased )
Most Declan's can also be found on social media sites, especially Twitter, where they speak of an unknown and certainly not recognised by any football authority, club called Sevco. Hence the reason most Declan's are also known as Sevcopaths.
Declan's only breed with Bernadettes who are generally related to their immediate family, for example a sister, niece, cousin, aunty or mother.
Football fan 1 : Would you look at the fucking state of that Declan over there.
Declan: pyoor shut it ya Sevco Zombie, Rangers are pyoor deid
