Lean burn vs rich burn are two different types of fule/oxygen mix scenarios for engines...maybe a reference to that? Rich burn is when just enough oxygen is provided for 100% fuel burn. Lean burn is when an excess amount of oxygen is provided.

"While lean‐burn gas engines are usually more
economical and powerful and operate at higher
loads, rich‐burn engines can achieve lower
emission levels with a single after treatment
and show a higher flexibility regarding transient
loads and ambient conditions"

It's obviously a reference to lean/rich, but (and I haven't watched Scott yet) I imagine if he said "engine rich" he was trolling SpaceX by suggesting that it was burning more than a stoichiometric amount of engine 🙂
