Poetry that avoids the use of regular meter is called "free verse." Meter refers to the pattern of stressed and unstressed syllables in a line of poetry, and regular meter means that the pattern repeats consistently throughout the poem. In contrast, free verse is characterized by a lack of a consistent meter or rhyme scheme.
Free verse poets have the freedom to use any arrangement of words and syllables they choose, allowing them to create their own unique rhythm and emphasis within each line. This often results in a more natural and conversational tone in the poem, with a greater focus on the meaning and emotional impact of the words.
Therefore, the answer is: free verse.
