If you go to a bachelor party and the first thing you do when you get back home is tell your wife or girlfriend about it, you are a d*ck!
If you think it is funny to send a picture of the strippers doing the dougie on the groom, you are a bigger d*ck!
If your idea of fun is destroying your friend’s life than you are a douche nozzle and should be removed from any future invite lists on Facebook. Just keep the party private, like it is supposed to be, and do not mention it to anyone, ever. Trust me, the women already know what goes on at bachelor parties, they just want you to say them out loud. It is a trap and you should do anything to avoid it.
