Ask him.
Unless of course I'm the sober friend you smashed off while drunk.
In which case, nuh uh.
Though, I'm not sure how much of a friend he is to, more or less, take advantage of you while you were drunk if he wasn't. Real (sober) friends don't smash off their drunk friends. It's kind of a douchey thing to do.
But yeah, you should ask him if it meant anything, but my guess is that he will either avoid the question or say "no" altogether. If it meant something, he'd wait to sleep with you when he's sure you'd remember it and you all could make it mean something...together.
Next time, just don't get drunk with lame friends who'll take advantage of you.
