Turtle neck Tac
This is when a 'Tic Tac' (sweet candy) is place inside the fore skin (turtle neck) and gently rolled around, hopefully getting some smegma on it. You then proceed by giving this tic tac to a victim without him/her knowing. It is important that you inform them after they have eaten it.
