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.
