Shegging is an advanced form of negging resulting in shagging.
The attribute of a shegger is the ability to
put her down to make her go down.
Once you have mastered the ability to
undermine a womans
confidence, disarming her feline powers, only to use them against her, you are eligible for the title of a shegger. Negging is the tactic. Shagging is the goal.
