Schlockmeisters are people who make or sell things that are cheap and of low quality, especially in the entertainment industry.
Schlockmeisters are usually seen in a negative way because they make things that are not very good.
Examples:
The schlockmeisters produced a really bad movie.
The toys from that store are made by schlockmeisters.
The schlockmeisters sell things that break easily.
The schlockmeisters tried to sell me a broken toy.
The schlockmeisters are known for making really terrible stuff.
I don't want to buy from the schlockmeisters because their things always break.
