plunger effect 

The act of fast paced and rapid anal pleasure, then a sudden removal of the penis (or other tool) from the anus. The outcomes are usually rather spectacular, as shit literally hits the fan (and everything else in its path).

Usually best enjoyed with 2 or more people.

Frank: Hey man, I heard your wife let you try anal with her the other night. How'd it go?

Dave: I pulled out too fast, and shit went flying everywhere, last time I try that..

Frank: aahh, the Plunger Effect

Plunger Effect 

The unclogging of shit in the anis during the act of anal, resulting in an eruption of poo.

"Bro, have you ever tried anal?"
"Nah fam, I'm way too worried about the plunger effect."
"wtf is that?"
"It's when you have a massive shit due to anal."
"wait, who has the shit?"
"The receiver...obviously. "

"hectic..."

the plunger effect 

When you make love to a girl on her period, and it significantly lessens the duration of the menstruation.

Due to the plunger effect of my penis in her vagina, the sheets got ruined, but her period was over in 2 days instead of 5, so I got to have sex with my wife during the Superbowl.
