[Vocabulary] What does mediocre mean?

[tatoearashiga]

I am confused whether mediocre means poor quality, average quality, slightly below average, or much below average.

I made up this example: You have a mediocre taste in buying clothes.

so how bad taste or average is the taste?

Does it give a negative connotation? offensive?
