The feeling one gets after eating a large meal from
McDonalds, together with a
large sugary soda and all the
extra condiments. It's a very nervous feeling, where your stomach feels uneasy and you have the McTwitches. It's a term coined by Morgan Spurlock in his documentary Super Size Me.
As
Morgan himself says in his
hit documentary, while eating a double-quarter pounder super-sized meal:
"See, now's the
time of the meal when you start getting the McStomach ache. You start getting the McTummy. You get the McGurgles in there. You get the McBrick, then you get the McStomach ache. Right now I've got some McGas that's rockin'. My arms... I feel
like I've got some McSweats goin'. My arms got the McTwitches going in here from all the sugar that's going in my body right now. I'm feeling a little McCrazy."
