Inflation means rising prices. The more demand in the economy the more prices go up. Hence over heating. What happened in the US was the fed printed trillions, a good chunk of which went directly to the consumer. This massive injection of money caused a huge spike in demand. It pushed the demand side something like 63 months into the future. Ie if you extrapolated the previous year on year increase of demand for goods. Usually when inflation is too high they will increase interest rates.
