It's just a rule when guys hear someone say 69 they say "nice" and then they laugh. It's a guy joke but the ladies get it too. Well, maybe some of them. We don't know why the "69" joke has taken such a popular turn with people in school but it is also funny among adults too. I guess you just have to have a dirty mind. Now we are assuming you know what 69 means in this context. If you don't you can go ask your mom. Maybe she will tell you.
