Bass Drop

Most of those are more than one sound.

Generally several loud transient 'impact' sounds
followed by a descending pitch glissando (slide)

You could get the first in a variety of ways, like smacking all 4 strings against the pickup with your open palm
the second you could simultaneously fret high up on the E or A string and after you make 'impact' slide down the string

You won't really get close though. Movie SFX guy have thousands of dollars of equipment, huge sample libraries and expertise in crafting and tweaking and combining each sample to produce that stuff. They get paid for a reason.

another point to consider:
The sound designer for the first Star Wars movie was asked how to make an explosion sound really huge. He said:
Make sure that , right before the explosion, it is completely silent.

So if you want to toss a 'bass drop' into a song, you must convince your band to leave space for it.
 
All the sounds in that clip are synthesized or created digitally. I have made sounds like that in Audacity, easily. Here’s how:
  1. Download Audacity. It’s free.
  2. Install all the DSP effects and plugins.
  3. Start with a source sound. A bass note would be perfect.
  4. Start playing around, applying effects, and undo if not helpful.
  5. After layering and applying manipulations that you like, you should end up with a satisfactory result.
