A way of neck-fucking someone by having them shrug their shoulder whilst you slide your dick in the space between the shoulder and side of head.

For when you get a kink in your neck.
Alexis Texas, if it doesn’t feel good, why would you still want to shirk jerk me?

Get the shirk jerk mug.
To avoid doing work while on the clock whilst taking care of one's needs. Less euphemistically: to jack off at work.
I was feeling really stressed at work today, so I locked my office and closed the blinds for a good ol' shirk and jerk to relieve my tension before the board meeting. Totally killed the presentation!
