This is a combination of keys, folowing a VVVVVV pattern, bouncing on the edges of the keyboard letters, that you type when you are so so , I meanlike, next level bored.
I was so bored I define the word qzectbumolp to see if anyone would do the same
qezctubmo is created by pressing two keys with a gap of one on the top row, then the bottom; then that sequence is repeated leaving a gap between each pressed key until reaching the left boundary of letter keys.
