Handy tool devised after feeling lousy at too many weddings. Planning ahead and consuming too much alcohol 2 days before the event where you need to be "on". Therefore, you will be hung over the night before the big day and won't be able to tie one on, thus avoiding feeling like crap when everyone else is partying.
"I feel terrible today because i drank too much at the rehearsal dinner. I won't be able to stay at the wedding very long. How do you feel so good?"

"Man, I pulled a rehearsal dinner trick...i got drunk on Thursday night so i couldn't drink last night. I'm good to go."
