The sewer line is blocked. Have a plumber come and inspect your manholes or run some rods down your sewerline from a rodding point to check what is wrong.
Toilets that bubble when flushed and drain slowly can be cause by different things, such as port holes that are clogged, a clogged drain line, the tank has a low water level, or a problem in the vent pipe. A plumber can check for the specific problem and fix it.
I do not know if popcorn can be flushed down the toilet. So, I wouldn't try it.- Ashton Smith
