The only real trick ones I remember are the ones during the final boss where the tells aren't concrete on a first viewing to know where the safety is going to be. Like Laserwhatever Decapitation. It's a donut AOE, but to me it looked like the first time that the draw in of the lasergun spindles were going to blow back the way they'd just drawn over the room.

So I guess what they mean by, "jebaited" whatever the heck that actually means is mechanics that you only get wrong once, due to ignorance on what their tell means/is.
