"Sometimes when one stares in the dark they might see a face and when they turn on the light to only see some pants in its place, that is the phenomenon of pants face."
"Damn those pants have one hell of a face, damn Pants-face."
for whenever you skip shaving and don't want anyone to know! its like when you forget to shave your legs and just wear pants, but now you can do it to your face -- with face pants! Pants for your face!
