When a male ejaculates on a sleeping females face, paying special attention to the eye area. When female awakes, she will find it difficult to open her eyes, as they have been "welded" shut.
I gave my bitch 'the welder' last night.
When you're inside a wet pussy and you get her to touch one side of the socket and you touch the other, so it arcs across the genitals.
Similar to the Electric Bob.
Sparks shot outta that pussy when I did the welder on her.
