the dull headache one gets after spending too much time in a shopping mall.
"Hey you want to grab a coffee?"
"Nah Cherise dragged me out shopping the whole morning, I've got a mallache from another dimension I need to lie down"
or
"Man I have to go buy my girl a birthday present"
"what a mallache!"
