McRighteous
1. Superficially faithful and/or spiritual; 2. Stridently and shallowly Christian.
Please stop being so McRighteous all the time, Jonah. Everybody knows you made an abstinence pledge.
McRighteous
A sandwich from Mcdonalds that is not on the menu. Very inexpensive. Where you order a McDouble and a McChicken and split the McDouble in half and put the McChicken in the middle and eat it. It is quite very delicious.
Dude, I just had a McRighteous and it was freaking sweeet!!
