Most often expressed in the form of pessimistic sentiments such as "XXXX was a horrible year, I hope next year will be better".

a "DeclineR" is an obese, ginger kid who spends all his time playing Halo. You may find many of these on what is called "Xbox Live" but there is only one true "DeclineR" and his "Xbox Live Gamertag" is "DecllineR".
