The 'Everything But' Misunderstanding

So a while ago I was out with a few friends and one of them recently hooked up with a new chick. He seemed excited about it or whatever and we asked him if he 'did it' with her. He said he hadn't-- but they did 'everything but'... He said he was kind of psyched about it because it was fun and it took the pressure off or whatever.

One of my friends was like, 'What do you mean you did everything but...' The guy who hooked up was like, 'We've been out like three times--- and the last time we did everything but...Everything but sex... Y'know?'  And this friend was like, 'No... I don't know! Everything but?! How's that work? How do you do everything but....?'

We were like, 'Dude wtf. Use your imagination...' He was like, 'I am! I don't get it!' The friend was like, 'We didn't have sex! We did everything but!' The confused friend was like, 'That totally count as sex!' I was like, 'That doesn't count!' He was looking at us like we were crazy. We were looking at him like he was crazy...

Finally it dawned on one of us that he was thinking the whole time, 'Everything butt! Everything butt sex!' That's what the confusion was about and that is the end of the story...

ok bye!
