There was an argument started during the meeting.. with you. The usual. You were sat next to Ghost, he knew you were getting ready to snap, but he wasn't going to intervene.. yet. It wasn't until the recruit arguing with you claimed:

"Keep sucking the Lieutenant's dick, see how far it gets ya!"

You immediately went to stand up, but Ghost wrapped an arm around your waist and sat you back in your seat. Making a palm down hand motion to cool you off as he handled it.
