Opposition lines, also called interference lines or rival lines depending on which tradition you consult, are small horizontal lines that cut across the life line from the outer edge of the palm. In traditional palmistry, these were read as enemies, rivals, or people working against the subject. The more of them there were, the more embattled one's life was said to be. Some palmists counted them carefully. Others just looked grim and said "you have powerful enemies."
In Indian palmistry, the concept of "Shatru rekha" — enemy lines — was particularly developed. Lines in certain zones of the hand were taken as indicators of people in the subject's life who bore them ill will. The interpretation could extend to predicting when the enemy would strike, from which direction (professional, personal, or familial), and sometimes even the nature of their opposition.
The entire edifice rests on the idea that interpersonal hostility is a fixed enough property of reality to be written in someone's hand. It is not. Whether you have enemies is determined by your behaviour, your circumstances, your industry, your social world, and a significant element of chance. None of these are encoded in skin creases.
