A non-penetrative sexual practice in which the penis is placed between a partner's thighs, armpits, knee-joints or digits of the hands and feet. Much thrusting takes place as in penetrative sex in order to quicken the temper of the male and excite him to climax. This 'knobbly' fetish has been practiced by a number of homosexual serial killers, Dennis Nilsen prominent among them. I myself once tried it with a girlfriend's armpit but it wasn't much fun to be honest.
Homeless victim: I suppose you're going to strangle me now?
Dennis Nilsen: All in good time. First I've got something to slip between your knee joints.
Homeless victim: Oh not bloody intecrural sex again! I'd rather be strangled.
