A rehearsal birthday is spontaneously given when the person with the upcoming birthday is in danger of buying the exact same gift that you have already gone to a lot of trouble to acquire.
"We had to throw a rehearsal birthday as Emma announced she was going to get a new skateboard today - I bought one for her 3 weeks ago."

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."

The time when you put on a suit / dress to make sure it fits before the big event. You leave the tags in so that you can return items that do not fit.

When sleeping next to your partner and you line up your butthole directly with a partner’s hole and fart. Their reaction let’s you know if the rehearsal was a success and you’re ready to move on to space docking.
I woke up my wife by lining up my butthole to her butthole to perform a NASA Dress Rehearsal before the space docking later in the month. She screamed that she felt the fart deep in her butt. I knew then, my years of preparation made me ready for the Space Dock. T-minus 20 days

The old dick you have to get, before you get all the new dick, because it's been a while since you had dick, so you have to reacquaint yourself with the ways of dick.
"We're definitely gonna have sex soon...I'm nervous though, I haven't had sex in aaaaaaages"

"You need to get yourself some rehearsal dick first, reacquaint yourself. Get the old little black book out."
