You probably don't want to know...but it's when two guys connect eachothers asses with a tube and shit in it and slide it back and forth into each others asses.
Eh, that's not as disturbing as the goat/////se man. Once you've seen that AND tub///girl, you're pretty much desensitzed to the internet. (Do NOT ask for links to those - if you haven't seen those pictures yet, consider yourself lucky)
As to the picture itself, I fear for the Falcon's safety..
That was Empire Strikes back. I wasn't saying that that sucked, I was saying that the actual Episode 1 that was made a few years ago sucked. Get it straight retard.
