Online games

i just joined a an online game website today, and i made a new friend, ok?
so we r at their "house" and then they are suddenly like "HEY YOU WANT TO HAVE ***" and i was like "... what?" ... "wait!" and then they were like "YOU WANT TO HAV S**" and i was like O_O and then left the "room" and then they sent me a message saying that they were just kidding and i was freaking out for like an hour because i believe that they were serious... im not going to join anymore random websites lol
