Short for intercrural sex, a non-penetrative form of intercourse that's increasingly popular amongst gay men. The male will place his penis between his receiving partner's thighs - usually with lubrication - and thrust to create friction. Among men who have sex with men, intercrural sex is also referred to as the "Princeton First-Year", the "Oxford Style", "Oxford Rub", or the "Ivy League Rub".
