Border compression is the opposite of what you think it is, actually. It's not about squishing borders into tiny little dots. No, no, no. It's about applying an invisible force field around the border, causing it to bulge outward in every direction.
Border stretching, on the other hand, is the art of making borders go long and thin. Like a cat in a bathtub. But, instead of water, you're dealing with pixels. It's a delicate balance between aesthetics and functionality, really.
