Declan 

Declan - A dick, secretly hates you, uses you to his advantage. Quite immature and dirty-minded, loves porn.

Boy 1: That dick Declan stole my wallet! I though he was my friend!
Boy 2: Dude, don't ever trust him.

Declan 

When shit in someone's rectum. Picture a french kiss, except instead of mouths it's asses, and instead of tongues its shit.

Damn, I just gave that bitch a Declan and I think I tore her a bit.

I just beat Timmy in a battle of the Declans and now he's all clogged up.

Declan 

A VERY annoying non human being who confuses the life out of EVERYONE and he is hated by many. Some ppl like him like his family but other than that he has barely any friend.

I feel sorry for declan

Declan 

A mouthy lippy punk. Often found at a vape shop or a taco bell. A person who doesn't know when to keep their mouth shut. One who feels empowered online but cowers when confronted in person.

Did you see what that dude said to me online? Just ignore him, He is a such a Declan.
