It is poetic in that words connoted, denoted and outright symbolized take on and exhibit meanings intended and non-intended by the author.
Text becomes texture and vice versa.
The act itself is loaded with poetic significance. What begins as merely a name being manipulated through letters and flung against a surface becomes perceived as a scream. An action, a license to seize. What begins as prank ends as poetry. The effort requires both improvisation and precision.
