When you use a bong or pipe after someone has used it for a spliff or mole bowl and get a head rush from the nicotine.

Jerking off with the non-dominant hand

Andrew, upon getting home from school Wednesday, attempted to shag his dog with his left hand, which he had never used before. Having missed out on years of practiced stroking, the left hand was inconsistent, uncooperative, and altogether an awkward and unfortunate choice. Andrew has decided that there will be no more jerking off with the non-dominant hand ever again.

I usually use my dominant hand to jack off with, unless I want to have a non-dominant hand jack-off session.
