Any sort of low quality 'leather' product (aka shitty leather, or shleather) more often found on cheap discount furniture that seemed like a good deal at the time however it turns out the 'leather' couch they sold you for $400 tears off easily from bored children and insane kittens, eventually making you resort to filling in the bare spots with Sharpie because you're having an open house or a party and don't want people to comment on the craptastic fatigue of your furniture.
Her: This couch hasn't held up very well at all.
