Stiction has been a part of the English language since at least 1946, when it appeared in a journal of aeronautics. While stiction refers to the force needed to get an object to move from a position at rest, it is not related to the verb stick. The word is a blend word formed from the st- of static ("of or relating to bodies at rest") and the -iction of friction ("the force that resists relative motion between two bodies in contact"). So, basically, it means "static friction" (or to put it another way, "stationary friction").
