On the 'typical' aircraft:
Pitch is the angle (from horizontal) along the of the
centerline of the aircraft.
Roll is the rotation around the centerline axis
Yaw is the rotation of the centerline around the 'altitude' axis
So your 'Rotate' would be akin to yaw, and so long as 'Pitch' relates
to the longest axis, both it and 'Roll' would be intuitive to someone
with an aerospace/aeronautical background (like me).
OTOH, your target audience may be better served with something
similar to Matthew Gerber's suggestions - 'Rotate about Z', etc.
