How can you annoy people in Minecraft?

From time to time I find it quite amusing to annoy other players on Minecraft servers and I wanted to ask if you might have some tips for doing so.

Especially in game modes such as bedwars, skywars, cookies, etc, I would be grateful for ideas

Do not worry, I do not want to take the players off the game, I want to take the excitement out of the game a bit and loosen up the game a bit.

TNT build a lot. You do not have to explain the rest.

Thanks, but I'm doing that already, I need more creative ideas.

Light wood houses with the lighter.

Cheating.

Fun and people get upset ^^
