Sex Position: When in the missionary position, the gentleman sits back on his knees, grabs the two legs of the lady, and brings them vertically together, as if she looks to be in a 'L' position. Then, he pushes the legs back, to where her knees are about touching her chest. At this point, the green light is on, and the trash compactor is initiated.
"Dude, I don't usually give girl's the trash compactor on the first date, but with her I had to pull out all of the stops."
Your girlfriend doesn’t shit for a weekand then you proceed to violently fuck her ass until the shit is nicely compacted into a shape of your choosing, then you freeze it and shove it back into her ass.
Yo bro I tried the Alaskan Trash Compactor with her last night and her asshole quivered when I stuck it in for the second time!
When you ask your partner to do anal and they say no because they have to poop and you proceed to do it anyway. You may also choose to do it "accidentally"
She said no again so I decided to give her a trash compactor. She never saw it coming.
