Liquid that emerges from someone's foot
Sally has been sent to the doctor with a case of Shoe paste.
When someone's face is exactly the same in every one of their photos/selfies they have a "copy-paste face". It's as if someone cut out their face from one photo and pasted it in every other photo.
Barb: look at my photos from my vacation in Vegas, Sharon! I had so much fun.
Sharon: *looks at photos* I'm sorry to tell ya, Barb. But you have a copy-paste face. You look exactly the same in every photo!
