Where you know you aren't full because you didn't eat to your capacity, but you ate McDonald's, so you feel absolutely horrible and sick to your stomach.
Today i had the urge for something light that could hold me over for a few hours, so i went to McDonald's and bought a burger off the dollar menu. After eating this i was so Mcstuffed i couldn't even have dinner...
