Really annoying and has a short temper. Usually plays vide games like rocket league. He runs once every 4 months and eats like shit after.

Get the Declanmug. Declan's are usually loud, obnoxious, and annoying. They think they are the greatest at everything even though they suck. Suck what you may ask? No, not suck on dick, but suck at literally every sport ever. Also they look horrifying, yet girls still think that he is handsome. I still don't understand women.
Girls: "Oh look Declan's here! Wow he's so handsome today."
Declan: "Yeah, I know."
Me, in the corner, standing by myself: "Declan's trash"
