Abusing the TF2 mechanic nobody knows about

There exists a TF2 mechanic so niche yet so powerful that I'm surprised I've not heard anything about it for the past 7 years. Certain textures (mainly metal grates) have a property called $compilepassbullets which leaves them completely solid but allows explosions to pass through them. Normally this isn't a huge deal since grate textures are rare, but with the addition of the new map Cachoeira, there's now a super easy way to rack up loads of kills against people who have no means of fighting back. Cheesy? Yes. Fun? Very much so.
