Booze and nudity were the memorable highlights. Tigers in the bathroom are overkill, just stick with the Cougars.
You need to let some time pass, the babies they had in high school aren't even weaned yet.
At my 20th, I was on the front porch of the building and had just inappropriately touched the hindquarters of one of my classmates (she invited me to do it - it was related to how I teased her in high school). Her husband was (whom I'd never met previously) . . . displeased. But that was not my problem because after that I was just standing there minding my own business when it happened. Another one of our classmates who was inside lifted her dress to her neck level and pressed everything she had against the window as a joke to the girls whose hindquarters I had just inappropriately touched. What she didn't know was that I was standing right there too. I enjoyed the sight. Drunk people are sometimes amusing.
