Rolling a Critical Miss has two effects: 1) Your attack is a Miss, not matter how low your THAC0 is and how high the target's AC is; and 2) There is a delay imposed before you can attack again. In BG1, this equates to losing the rest of your attacks in that round.
If you are in Stealth and trying to Backstab someone, normally you have time to take 2 or 3 swings before the last of your Stealth runs out. But if you roll a Critical Miss, you become visible immediately--essentially, you swung too wide, you lose your balance and fall flat on your face, with a loud "OW!" This would probably alert the bad guy that there's someone behind him. (Of course, actually *hitting* the guy with your Backstab brings you out of Stealth as well.)
