Repeatedly and obsessively engaging in a SIMPLE behavior or motion, like pulling at one's face to remove imagined objects that aren't there. Persons addicted to methamphetamine will engage in this type of compulsion. Yet, it is a myth some people subscribe to , that the behavior can extend to having sex. People high on meth can't perform anything NEARLY that complicated when they're tweaking, let alone maintain an erection or climax.
He must be tweaking like crazy, to have done that to his face!
