What strain hit you way harder than you expected?

You ever grab a new strain thinking it’ll be a chill sesh, and then it completely steamrolls you? I picked up some Ice Cream Cake recently expecting mellow couch vibes, and instead I spent 45 minutes contemplating whether time was even real. I’m curious, what’s a strain that totally caught you off guard? Could be in a good way or a “why am I sweating and staring at the microwave” kind of way. Looking to add some heavy-hitters (or weird experiences) to the list.
