means To show off deliberately, performing for attention rather than for the task at hand.

from From the literal showboats — flashy riverboats that traveled the Mississippi and other American rivers in the 1800s, staging theater and variety shows for towns along the banks. The boats were built to dazzle from a distance, all paint and spectacle, docking just long enough to put on a show before moving on. By the early 1900s 'showboat' had drifted ashore as a verb, describing anyone who performs for the crowd the way those boats performed for the riverbank — loud, bright, and gone before you could ask if there was substance underneath.
