The term beach party is used for times when a large group of people are all in a bad mood at once. This is called a beach party because it appears that everyone in the group has traved to the beach and has collected a large a amount of sand in their vagina.
"God it was such a beach party at work today, everyone was bitting each others heads off, and the floor was covered in fish scented sand"
