You have a 1 in 8 chance of making your hand. if your opponent raises to 5xBB, and his stack is only 25xBB, calling with a low pocket pair cannot be profitable, because you are basically looking at losing 5xBB 7 times, and winning 25xBB 1 time, therefore having a net loss of 10BB. Obviously if you have a short stack, the same thing happens. Something else to consider, is realistically you will not get 8 times the preflop bet after the flop, sometimes they will fold. So, it is a good idea to make sure that they have well over 8 times the preflop call amount, (which is common as most people have ~25 times the amount), that way you might make back 20x your raise one time, and it will make up for the times you don't make what you should've.
