Sheep Shocker 

The Sheep Shocker is when you're engaged in vaginal sex and as you're about to ejaculate you shock her in the butthole with a taser causing her to shout "baaaa".

I gave Jasmine the sheep shocker last night and she yelled "baaa" so loud it woke up the neighbors.

I couldn't even see him with his girl last night because of his shacker sheet.
