look up any word, like bae:
The result of eating too much fast food, burgers in particular, causing the sweat glands to sweat 'pickle' sweat. Picklesweat is commonly found on windscreens in vehicles with fast food junky owners. It can be recognised as a greasy film coating the inside of the window.
Craigo: "the phat chick that sold me this car ate bulk fast food yo. She musta breathed grease all over this windscreen cause I cant shite out of it!"

T-Dog: "bro thats some serious picklesweat"
