What is a coffin-corner and how does one get into it in the pattern?

The "coffin-corner" is where you end up when the wind is blowing you
out from the runway on your base-to-final turn.

Your instinct is to tighten the turn in an effort to keep the runway
aligned, and maybe help it along with some rudder. This can be
disastrous at slow speeds while close to the ground, since a stall/spin
can develop quickly, and you won't have sufficient altitude to recover.
