Retaliation Penetration 

Another word for "Hate Fucking" a person. When you dislike someone so much or are mad at them you bang them as hard as you can; taking out all your anger and frustration on them then kick them out of bed and make them go home once your done having your way with them.

Andrea is such a dirty skank, she went behind my back and tried screwing my best friend Jake. So tonight I plan on getting a little "Retaliation Penetration" done on her ass then breaking up with her!

quadruple penetration 

Much like "Double penetration" and "Triple penetration," it is the act of 4 male genitals entering a females body through each "hole," at least one "hole" will have two male genitals inside. "Hole" refers to the female vagina, the anal hole, or the mouth.

"Quadruple Penetration" may be prominent in something like porn.

penetration 

-To expand one's sexual horizons

-Forceful insertion of a flashdrive that doesn't quite fit in the USB port.

-That moment when your key doesn't fit in the keyhole, because it's the wrong key to begin with, so you shove that mother fucking bitch up in there.

-When you ram that big ass rhino horn into the tree. (Also see gay penetration )

Ben's penetration game is so strong. Headbanging with his 69 pringle-length wanker is a good time.
