Footsies is a practice in which two people use their feet to play with each other's feet in their pants. This generally involves slipping their shoes off under a table and rubbing their feet against one another or up their partner's leg. Women and men commonly engage in this activity, while women will sometimes play footsie with other women as well. Men generally do not do so to other men, but it is less taboo among gay or bisexual men. There may or may not be an erotic or flirtatious sense to the game.
