Declan 

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

Declan 

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?
