Smooth Move, Ajax 

When someone makes a bad or awkward decision (move).

“Smooth move” - Sarcasm. The move was indeed, not smooth

“Ajax”- Ajax is a rough cleaner, similar to comet. This part is more metaphorically literal, because it is comparing the target’s actions to one of the roughest household items
