weird situation in home game

[DaveyDonk]

I was just in a home game playing some NL, it had gotten kind of wild and people weren't paying a whole lot of attention at times. I was in the SB and most of the 10 people at the table limped, I completed, we see a flop. It comes, checks around to the dealer who bets. I call, someone else calls, and the dealer burns and turns. It gives me a good draw, so I pop out a bet, next person folds, then the person who was in the CO seat says "I'm still in, and I woulda called" and puts in the $4 or whatever the flop bet was. Then he raises allin, I call w/ my 4 billion outs and he flips over a straight, which he would have been calling a gutshot on the flop.

Does anyone know what the "official" ruling would be for something like this? I didn't care too much, as its a friendly game, and that guy was hopped up on painkillers and alcohol since he got 2 of his fingers partially cut off a week earlier! I didn't want to raise a fuss due to these reasons, but should I have at the time I bet the turn? If so, what could have been done? Thanks!
