shafting
n.— «A young dentist boasted to a friend that he had taken six ecstasy tablets and was heading to the toilets to insert another into his rectum so that it would be absorbed faster. The conversation was shocking to some who overheard it, but “shafting,” as it is known, has emerged as an alternative for those who do not wish to take their ecstasy orally.» —“Ecstasy can be agony and soft message is no help” by Caroline Marcus Sydney Morning Herald (Australia) Jan. 8, 2007.
