while doing a girl doggystyle, you reach out and use your index finger to pull her nose up and then yell "take the full length Sissy!"
If you're gay its called a Kevin Bacon
Oh man, I heard Brian was doing Nancy doggystyle and gave her a Sissy Spacek last night. He's hilarious.
you need three people to pull this one off. make sure you have a camera nearby as this is a very rare stunt to pull off. first, you get jessica simpson to get naked and bend over. then the second person holds a bucket of dry ice under her ass. then you back up and kick the dry ice up her butthole like a punt-kicker. volia'..sissy spacek.
man #1: it's a good thing i had so much blow on me last night.
man #2: why's that?
man #1: how else would i have convinced jessica simpson to participate in a sissy spacek with my buddy and i?
man #2: gee, i wish i were there to see that.
man #1: indeed.
