I take a lot of ideas for bass drops from mathcorecore breakdowns.
Yes, it's weird to dance, but for a bridge when things get intense it's the shit.

Symmetric diminished.
You can use it to modulate to a lot of tonalities and it is used in a lot of hardcore breakdowns (althought they don't even know it ).
In dubstep is used a lot (for me at least), because the bass drops have a lot of tritones and (maj7).
