Deep Note 

That awesome mind-blowing noise you hear in every movie theatre before the movie starts. It's the iconic sound where it starts off quiet but then crescendos into this epic sound comprised of 30 synths simultaneously playing the same note at a huge octave range. It is often accompanied by epic high-quality stunning visuals. When you hear that, you know you're in for a treat of the best cinematic experience ever!

Guy: I think I've just found the most pleasing sound in the entire world

Girl: What is it?

Guy: *plays THX Deep Note*

Girl: *immediately gets wet AF*

Deepnoting

When you perfectly time intercourse with your partner at a movie theater to the THX Deepnote sound effect plays.

“Hey baby guess its time for some deepnoting”
“Tucker your family owns this theater”
