"Pull up and go around" is the correct phraseology.
I usually hear
"pull up and go around for practice" at YKZ or "pull up and go around traffic still on runway".
I woulda thunk that the "pull up" portion of the go around would be a given. Guess not. Its kinda like saying Cleared for takeoff and pull up once reaching rotation speed. But thats just how us crazy cowboy Americans do it anyway.
Oh, and don't forget "cleared to land and decelerate on the runway"
