Doesn’t matter how old you are, when you have to say his cox out loud, you laugh. Or at least you better. Can’t trust people that don’t laugh at this type of humor. Like when the number 69 comes up in causal conversation. Protocol is to look right at your closest friend in the room immediately. Smirk and hold in laughter. If you see someone doing that and you say “what?” You just don’t get it.
