Zombie Mat
A laundromat that is gross, dirty, disgusting, scary, or where you don't want to go to. Commonly will have broken or out of service washing machines, old equipment, and an overall hostile environment. Equipment is unclean (disease can spread), and probably hasn't been cleaned in a couple of months.
No I don't want to go there. That place is a disgusting Zombie Mat. Let's go to WaveMAX® Laundry instead! It's always clean in there.
