anal shock 

when you are on the toilet and you finally release a larger than normal lump of coagulated feses, and the resulting splash from the toilet bowl projects up and into your feses softened anal cavity, resulting in a jumping or startling motion and the flexing of muscle tissue in the arms and legs.

i was feeling really good because i was holding in this gigantic poop all day, then right as i shit i got a massive anal shock. i probably twitched for about a minute afterwards.

anal shockburst 

An anal shockburst is what happens when the shit streams out of your ass at such a speed that it briefly crosses the sound barrier, resulting in a sonic boom that plasters the porcelain with brown chowder and scares your family in the next room.

"Uh oh, it sounds like Billy just let off an anal shockburst. Better call the plumber."

anal-berger shocker

The act of inserting 2 fingers into the ass, and 1 into the vagina. This is usually performed when she is laying on her stomach. This is the inverse of the common shocker. Only the kinkiest of slampigs will ask or allow for this to happen. Commonly described a number of ways, for example 2 in the stink, 1 in the pink. Attempting this move on a slampig not directly asking for it is reserved for those of the highest bro king status as this can very easily backfire and for those trying to degrade women as much as possible.

I went in for the shocker but the chick flipped over and begged for the anal-berger shocker.

My night got really weird when the slampig I was with asked me to give her the anal-berger shocker.

Friend 1: How did your night end up?

Friend 2: It was going well until I went for the anal-berger shocker and I got a hair iron thrown at me as I ran through the dorm naked holding my clothes over my crotch as everyone came out to view my shame.
