Killing time in Computer Lab

Some guy who is not in my class was sitting next to me in the very crowded computer lab.  He was bored.  He had an official drug manual next to him on the desk, and his phone was in his lap.  I heard  him typing furiously and looked over to see this:

I have not seen anyone over the age of 10 ever do that.
