Poll: which trap mechanic does the community find to be the most annoying

With all of the youtube videos documenting the absurdity of AP maokai and the power of his saplings, it made me wonder: what is the the league community's least favorite trap? Now the rough definition that I will use for trap is any spell that lasts a long time (let's say 20+ seconds), requires no interaction on behalf of the players, and is triggered when an enemy player, pet, or minion is within proximity. That gives us 5 traps that come to mind(please feel free to correct me in the comment and I will amend the post to include if I agree that it fits my definition of a trap). For those of you who need a refresher on the traps: Caitlyn's yordle snap trap: These traps last 90 seconds and will root a target in place for 2 seconds, grant truesight, and grant caitlynn a headshot procc on the target for extra bonus damage depending on the rank. Maokai's sapling toss: Maokai tosses a sapling at the target location and after a short arming duration, will run towards the first enemy target that is close enough to trigger it and then it will explode, doing flat magic damage plus an amount that scales with the enemy's max hit points while slowing the targets for 35%. When placed in the brush, the damage will be dealt over 2 seconds and the damage dealt will be doubled. Nidalee's Bushwhack: nidalee places a trap at the target location that will cause magic damage over 4 seconds to the target. Additionally, nidalee will gain the ability to pounce on the target at an increased range. Shaco's jack in the box: Shaco will place an invisible box on the ground that will arm after a short delay. When an enemy target approaches a box, the box will trigger causing a short duration fear followed by a constant barrage of ranged attacks from the box that will last until the box is destroyed, the box times out, or the target leaves the range of the box. Teemo's noxious traps: teemo drops a poisonous mushroom that will stealth and arm after a short delay. When an enemy target is close enough to trigger the trap, the trap will explode, causing damage over 4 seconds and slowing the target based on rank for the duration.

I really am not interested in hearing complaining about game balance or the fairness of a mechanic. However, if you can explain WHY you dislike a particular trap over the others, I am interested in hearing it. The poll is simply about which one you may find the most annoying, so there is no wrong answer as what grinds your gears may not phase somebody else.

If anyone was curious what OP's choice was; I dislike shaco's boxes the most. Shaco tilts me in everything he does from his stupid dance, to his annoying voicelines, to the various parts of his kit(invisible flash on a low cd, free crits based on positioning, the option to take smite/ignite and cheese...etc). So this is more about shaco than the trap itself. What an annoying Joker wannabe. -_-

Edit: I forgot to include jhin's trap. for those who forget like I did, jhin places a trap on the ground that arms and stealths after a moderate delay. when an enemy target steps on it, they will be slowed while the the trap will detonate for a large amount of damage after 2 seconds
