Giving your grandpa a blowjob and having him shoot his load in your mouth.
"Man grandpa, I sure love when you give me a blast from the past!"

1.
A show involving bright lights, a dark stage, mics that don't make anything loud unless you're backstage, cursing with your headset accidentally on. It is custom-made costumes that are 9 sizes to big or 4 sizes too small, it is the reason why we stay at school until 9 on a weeknight. It is dancing, it is singing, it is working hard for 2 months just to walk out of the dressing rooms and get a flower from the guy who swore he'd never be caught dead in that auditorium. It is showing the assholes that a freshman can get a solo and be better than half the seniors. It is that place we go to to whine about having to stay and cry when at the final end, it's time to go. A place where even the most perverted geniuses are forever respected. In the end though, "Y'all suck."
"Blast from the Past is the only thing that could make me wear purple spandex."

Watch what you eat at the garlic festival, unless you wanna rip a ripe blast from the past at work tomorrow.

a blast from the past is when you hook up with someone you previously dated or had history with and bust a nut on her.
"remember my ex from high school? i met her at that party and i gave her a blast from the past"
