Dirty data in a database management system (DBMS) refers to data that is inaccurate, incomplete, or inconsistent. This can include missing values, duplicate records, formatting errors, or outdated information. Dirty data can lead to mistakes in decision-making and analysis, so it's important to regularly clean and maintain the data in a database.
The foremost problem that can occur is the "loss of data" due to interference or the data collision that causes corruption of data...

Whenever your hand is dirty or greasy
db writer(DBWn) writes dirty buffer(modified data) into datafiles on disk.
Processing occurs after data have been entered into the computer.
Data collisions occur when data is transmitted on the same medium at the same time. Therefore, to avoid data collisions, connect all hosts to a full duplex switch.
Dirty spark plugs can occur on any make, model, or year. Changing the spark plugs should be done for maintenance, such as when you do a tune up.
