A pity fuck is when someone engages in sexual intercourse with another person based on feelings of pity rather than sexual attraction. Although sex can be a way of comforting and caring for someone, this term is often used in a disparaging way. It may imply that the person receiving the pity fuck isn't deserving of sex or attraction in some way. Pity fuck may also be an excuse people use after the fact to explain sex they had with a partner they feel ambivalent about.
