A shircle is a mishapen circle that's not quite an oval. Thus, a shircle jerk is a mishapen circle jerk.

Smircle Jerk 

A group of men standing in a circle masterbating much like "circle jerk" however with this version each participant must be holding a half smile or a smirk to make things even more enjoyable.
